The best griddle cover for outdoor storage is a 600D polyester cover with a waterproof or water-resistant coating, reinforced stitching, side straps that anchor under the frame, and air vents that let trapped moisture escape. Anything less and rain, UV and condensation will find a way into your steel.
Flat-top griddles are bare cold-rolled steel. Park one on a patio, driveway or deck for more than a few days and the surface starts oxidizing, first as a faint orange bloom, then as pitting that no amount of scrubbing fully removes. A cover is the single cheapest thing you can do to push that clock back.
We spent weeks comparing ten covers built for outdoor storage, measuring fabric weight, seam construction, strap hardware and vent placement against each other and against the complaints owners actually post about. Several cover brands out there solve for a nice photo, not for a griddle that sits through a wet winter. These ten do the real work.
One thing to clear up early: all ten picks in this roundup are fabric covers, because that is what protects the cooking surface in real outdoor storage. A molded hard shell is a different product for a different job, and we explain where it fits further down.

The table above is sorted in the order we discuss each cover below, not by rank. Every entry lists the fabric weight and the hardware that actually holds it down, because those two details decide whether a cover survives a season outside.
1. Blackstone 36 inch Griddle Cover – Best Overall for Outdoor Storage
Pros
- Heavy-duty 600D polyester with double-layered construction
- Poly-resin buckles clip under the base and hold in wind
- Form-fitted profile looks tidy on a patio
- Wipes or hoses clean easily
Cons
- Custom fit only to the Blackstone 36 inch with shelf attached and the Tailgater
- Buckles must be unclipped from under the base every time you cook
- Water-resistant rather than sealed-seam waterproof
This is the cover I recommend first, and the reason is boring and simple: it has the deepest review pile in the category and the highest five-star share, with 29k+ reviews averaging 4.8. When something has been on enough porches in enough states for that many people to write about it, the failure modes show up in the reviews rather than in the marketing copy.
The build is 600D polyester with a water-resistant outer coating and double-layered construction with reinforced stitching. It weighs 3.8 pounds, which is enough fabric to feel substantial in the hand without being a chore to wrestle over the cooking surface.
The detail I like most is the fastening. These are poly-resin buckle straps that clip under the griddle base, not hook-and-loop or an elastic hem, so once they are under there the cover is not going anywhere in a gust. That is the difference between a cover that protects a griddle and a cover that decorates one for a week.
Owners report water beads on the surface and wipes or hoses clean, and the black dye does not fade. The fabric is described as heavy-duty canvas that resists fading and cold cracking, which matters more than it sounds in a climate that drops below freezing with the cover on.
What to check before you buy?
This is a model-specific cover. It is designed for the Blackstone 36 inch griddle with shelf attached and the Tailgater, and it will not fit a 36 inch griddle from another brand, a 36 inch ProSeries, or a hooded 36 inch station. Measure your unit and confirm the shelf is attached before you order.
Second, expect to unclip the buckles from under the base every time you want to cook. That is the cost of the wind security, and after a season it becomes muscle memory. It is also a reason this cover suits a griddle that stays covered more than it cooks.
Where it falls short?
It is water-resistant, not sealed-seam waterproof. In sustained driving rain you will want to know that the seams are stitched rather than taped, because a stitched seam is the weak point in a heavy rain event.
It also has no venting, so on a still day after a warm afternoon it can hold a little trapped warmth against the surface. In our view that is a fair trade for the buckle security, but it matters if your griddle sits in a spot that gets no airflow at all.
2. iCOVER 36 inch Griddle Cover – Best Value Across Brands
Pros
- Fits a wide range of 4-burner flat tops including Blackstone
- Camp Chef and Weber
- Water-repellent finish hoses clean easily
- Bottom drawstring adds a second layer of wind security
- Entry-level option with a 51k+ review base
Cons
- Thinner fabric than the 600D and 1000D covers in this roundup
- Lowest average rating here at 4.4 with 5 percent one-star reviews
- Will not fit the Blackstone 36 inch ProSeries
If you own a 36 inch four-burner flat top and you are not sure which brand it is, this is the cover that removes the guesswork. It is sized 65 inches by 22.5 inches by 26 inches and is listed as fitting Blackstone 1554, 1560, 1565, 1825, 1836, 1819, 1868, Camp Chef FTG600 and Weber 44310401.
It carries more reviews than anything else we looked at, over 51k, and it is the top seller in its category. That volume cuts both ways, and we will come back to why, but it does mean you can read a large number of owner reports before deciding.
Construction is oxford polyester with a water-resistant PVC coating and a UV-resistant outer vinyl coating, with double-reinforced corners at the sharp elbows. Those corners are where a cheaper cover always fails first, because that is where the fabric bends every time you pull it on.
Wind security is a two-part system: buckle straps on both sides plus a bottom drawstring closure. The drawstring is the piece most covers skip, and it is the piece that stops a cover from ballooning and lifting at the hem.
What to check before you buy?
Measure first, because this is a universal fit with real limits. It does not cover the Blackstone 36 inch ProSeries, and the listed dimensions are tight enough that a griddle with a raised handle bar or a deeper side shelf can crowd the seams.
Also expect a lighter fabric than the top of this list. The reviews repeatedly point to durability and fit precision as the two recurring gripes, and the fabric here is thinner than the 600D and 1000D covers elsewhere in this roundup.
Where it falls short?
The 4.4 average is the lowest here, and about 5 percent of reviews are one star. Most of those complaints trace back to fit and long-term tearing rather than waterproofing, which is the expected profile of a thinner universal cover.
There are also no air vents, so this cover relies on the water-repellent finish rather than on airflow to keep moisture off the steel. It works best in a location that gets sun and moving air after a rain rather than sitting damp in shade.
3. ATHLEEGOUS Griddle Cover for Blackstone 36 inch – Best Multi-Brand Oxford Build
Pros
- 600D Oxford cloth rated above 210D and 420D constructions
- Waterproof coating and reinforced stitching limit pooling
- Heat-resistant PU fabric limits heat buildup
- Three straps give the strongest wind security at this size
Cons
- Will not fit the Blackstone 36 inch ProSeries
- Hook-and-loop closure can wear after extended exposure
- Only offered in black at this size
This one sits in the middle of the pack on price and near the top on construction detail, and the spec sheet is unusually specific about it. It is reinforced 600D Oxford cloth, and the listing states plainly that it is rated above 210D and 420D constructions, which is exactly the kind of claim most listings leave vague.
It measures 66.5 inches long by 22.44 inches wide by 25.98 inches high, built for the Blackstone 36 inch griddle without a hood, and it is also listed for Blackstone 1554, 1565, 1825 and 1868. The matching 28 inch version with a hood is offered in the same line.
Two features here are worth more than they look. The first is a waterproof coating paired with reinforced stitching for a tight seal, which addresses the seam weakness that shows up in every universal cover we tested. The second is heat-resistant PU fabric that limits heat buildup, so a cover sitting in direct sun is less likely to cook the trapped air underneath.
Security comes from adjustable dual side straps plus an additional bottom strap, so three anchor points rather than two. Owners with genuinely windy patios rate that combination highly.
What to check before you buy?
Confirm your griddle is not the ProSeries. That model is excluded, and the failure mode when you skip this check is a cover that fits everywhere except the part that matters, which is the top surface edge.
Also think about the hook-and-loop closure. It is quick and it cinches tight, but hook-and-loop is the first thing to degrade after a few seasons of wet, sun-exposed outdoor use, and replacement straps are not always available separately.
Where it falls short?
At 4.5 across nearly 10k reviews, this sits a little below the leaders on satisfaction, and about 71 percent of its reviews are five star. Reviewers most often flag compatibility confusion at the time of purchase rather than a defect in the cover itself.
Color is another limitation. At this size only black is offered, so if your patio is light stone or wood and you want the cover to blend rather than read as a black box, that is not adjustable here.
4. NettyPro Griddle Cover for Blackstone 36 inch – Best for Ventilation and Sealed Seams
NettyPro Griddle Cover for Blackstone 36 inch Griddle, Waterproof UV Resistant 4 Burner Flat Top Gas Grill Cover 36″ Cooking Station, Black
Pros
- Seam-taped PU coating holds out heavy rain
- Covered front vent reduces condensation
- Quick-release buckles stay secure where hook-and-loop fails
- Generous sizing drapes well
- Available in three colors across 30-plus sizes
Cons
- Lighter colorways fade faster than the fadeproof claim suggests
- Webbing can weaken over several seasons of UV exposure
- Vent opening may admit small pests
This is the only cover in the roundup with fully seam-taped construction and a wide covered front vent, and those two features together answer the two biggest complaints in the category. Seams are where universal covers leak. Vents are where covers trap the moisture that causes the rust they were bought to prevent.
It measures 67 inches long by 27 inches wide by 32 inches high, which makes it one of the more generously sized covers here, and the listing says it fits most 4-burner Blackstone and Weber models. The extra width is what lets the fabric drape rather than pull taut across the corners.
The fabric is high-density, fadeproof and UV-resistant with a PU coating, and the edges are double stitched. Hardware is two adjustable side straps plus four bottom buckles, which is more anchor points than any other cover we reviewed.
Because quick-release buckles replace hook-and-loop, this is the cover we would pick for a location that gets real weather. The closure does not turn to fuzz and lose its grip after a wet winter the way hook-and-loop does.
What to check before you buy?
Check your width, not just your length. At 27 inches wide and 32 inches high this is sized for a full 4-burner station with side shelves, and one owner had to remove side bars to get it over their grill. Slimmer single-shelf units will find it loose.
Then decide how you feel about the vent. The covered front vent is what stops condensation, but long-term owners note that small pests can find their way in through the opening, which matters if you are in an area with mice or insects.
Where it falls short?
Long-term owners report that the brown colorway faded noticeably after about five years in full sun, which is faster than the fadeproof claim implies. The webbing also weakens over several seasons of UV exposure and can tear when pulled across a sharp grill corner.
It is a fabric cover, so in a severe storm it will still move. The six anchor points make that unlikely, but nothing soft stops a direct gust the way a hard shell does.
5. Unicook Griddle Cover for Blackstone 22 and 28 inch – Best for Smaller Griddles
Pros
- Thick heavy-duty fabric that has held up against hail and sun
- Center support design stops water pooling on top
- Hook-and-loop straps cinch the cover on in seconds
- Integrated handles for fitting
- hanging and storage
Cons
- Will not fit the Blackstone 28 inch ProSeries or models 1856 and 1924
- Velcro straps can tear away after a couple of years
- Not machine washable
Most covers in this roundup are 36 inch covers because that is where the demand is. If you own a 22 inch portable or a 28 inch single-shelf griddle, this is the one to look at, sized 45 inches long by 23 inches wide by 25 inches high for the Blackstone 28 inch single-shelf griddle and Nexgrill equivalents.
It carries a 4.8 average across just under 8k reviews, which puts it in the top tier for satisfaction, and the same manufacturer runs eight size variants from small single-shelf units through large six-burner stations, so a lot of owners end up owning two.
The fabric is heavy-duty fade-resistant polyester with a waterproof vinyl lining, and the seams are closed with hot-melt sealing tape rather than stitching alone. That is a real upgrade over a stitched-only seam in a hard rain.
My favorite detail is the center support. It runs along the top ridge and sheds standing water off the cover instead of letting it sit in a flat pool, which is the single most common way a griddle ends up with water on it under an otherwise good cover.
What to check before you buy?
Compatibility is the catch. It does not fit the Blackstone 28 inch ProSeries or the shelf models 1856 and 1924, and those are common enough 28 inch units that this trips people up. Confirm the model number before ordering.
Measure height too. At 25 inches high it is sized for a single-shelf griddle, and a unit with a taller cabinet or a raised handle bar will not sit under it cleanly.
Where it falls short?
The hook-and-loop straps are the weak point over time. Owners report they can tear away after a couple of years, and the good news is the cover often stays on anyway because of the fit, but the cinch is what keeps water out of the sides.
It is also hose clean only, not machine washable, so plan to clean it where you are rather than in a laundry room. And like most covers, it has no vents, so the center support doing the water shedding is carrying more weight than usual.
6. Blackstone 5482 Griddle Cover for 36 inch Hooded – Best for Hooded Stations
Pros
- Highest satisfaction score in the roundup at 4.9 with 92 percent five-star
- Thick 600D polyester owners describe as premium
- Side clips and cinch straps lock the cover down
- Backed by a 1-year manufacturer warranty
Cons
- Sized only for the 36 inch griddle with hood
- Weighs 6 pounds
- heavier than every other cover here
- No cross-brand compatibility
If your 36 inch griddle has a hood and a propane tank attached, this is the one built for it, and the hood is the reason a generic 36 inch cover never quite fits. Hoods add height, a hinge line and a stack of moving parts that a universal cover cannot account for.
It holds the highest average rating in the roundup at 4.9, with 92 percent of its reviews at five stars and essentially no one-star feedback at all. Owners describe the material as noticeably thicker and heavier than generic covers, and that impression matches the 6 pound weight of the cover itself.
The fabric is heavy-duty 600D polyester with a weather-resistant treatment and reinforced stitching to prevent leaks and tearing. The profile is form-fitting to the 36 inch griddle with hood, so the fabric follows the shape rather than ballooning around it.
Fastening is cinch straps with plastic clips, and owners report the cover stays locked in high wind. The clips matter here because a hood creates lift, and a cover that catches air above the hood is exactly the kind that ends up in a neighbor’s yard.
What to check before you buy?
Confirm you have the hooded 36 inch model. A hoodless 36 inch griddle needs a different cover, and this one will not drape correctly over a flat-top station with nothing above it.
Also accept the weight. At 6 pounds this is the heaviest cover in the roundup by a wide margin, and for an owner who covers and uncovers the griddle several times a week that is a real ergonomic cost.
Where it falls short?
It is entirely brand-specific. If your griddle is a comparable size but from another manufacturer, this does not help you, and that is the trade you accept for the close fit and the plastic clip system.
Like the other fabric covers here, it has no vents, so it depends on airflow after a wet spell. It is also water-resistant rather than sealed-seam waterproof, so in a long driving rain you may want to run a hose over it afterward.
7. Blackstone 5483 Griddle Cover for 28 inch Hooded – Best 28 inch Hood Fit
Pros
- Owners describe the 600D fabric as closer to backpack material than a big-box tarp
- Water beads on the surface and the interior stays dry
- Semi-elastic clinch straps and buckles hold through thunderstorms
- Generous fit covers the propane tank and front shelf together
Cons
- Sized for the 28 inch griddle with hood only
- New fabric creases take about a day of sun to relax out
- Can run slightly long and make the griddle awkward to move
The 28 inch hooded griddle has the same problem as the 36 inch hooded one, and this is the dedicated answer. It is designed for the Blackstone 28 inch griddle with hood and similar models, and the generous fit means the propane tank and front shelf sit under one roof with the cooking surface.
At 4.8 across 3,573 reviews with 89 percent five star and no one-star ratings, this is one of the cleanest satisfaction profiles in the group. Owners consistently report that water beads on the surface and the interior stays dry, including at the hood hinge where covers usually leak first.
Construction is heavy-duty 600D polyester, fade-resistant, with a water-resistant PVC coating, plus semi-elastic clinch straps and clips. The semi-elastic section is the useful part: it takes up the slack between a fixed-size strap and a fixed-size griddle, so the fit stays tight after the cover stretches through a season.
Owners also note that the generous fit tucks under the base, which blocks wind and insects, and that the black dye does not fade when the cover is hosed down.
What to check before you buy?
This is the 28 inch with hood only. If your 28 inch griddle is a shelf model or a ProSeries, you need a different size entirely, and the fit will not be close enough to make the difference work.
Read the long-term owner notes too. Several people say the cover runs slightly long, which means the griddle is more awkward to move with the cover fitted, and that matters if you wheel it out from a garage rather than carrying it once a season.
Where it falls short?
New fabric arrives creased, and it takes roughly a day of sun for the creases to relax out. That sounds trivial until you try to fit a rigidly creased cover over a hooded station and wonder whether it is going to reach.
It is also among the more expensive 36 inch covers in the roundup, and the premium is mostly paying for the brand fit and the warranty rather than for fabric weight beyond what the 600D covers elsewhere already deliver.
8. ULTCOVER 600D Waterproof Griddle Cover – Best for Wide Two-Shelf Fits
Pros
- Sized for 36 inch griddles with two side shelves and a hood up to 67 by 28 inches
- 600D canvas with waterproof backing blocks rain
- hail
- snow
- leaves and droppings
- Structured side vents reduce condensation and billowing
- Elastic draw cords and clips anchor to the wheel legs
Cons
- Must wait for the griddle to cool fully before fitting
- Sized for hooded two-shelf units so it is loose on slimmer ones
- Only one color shown at this 36 inch size
This is the widest cover in the roundup at 67 inches long by 28 inches wide by 32 inches high, and that width is the point. It is built for 36 inch griddles with two side shelves and a hood, and the listing names Blackstone, Halo, Nexgrill and Weber among the units it covers.
A wider cut sounds like a small thing until you own a griddle with shelves that stick out. Most universal 36 inch covers are sized to the body of the griddle, which leaves both side shelves bare and exposed, and a bare side shelf is where rust starts on a lot of units.
The fabric is 600D polyester canvas with a waterproof backing, and it is described as blocking rain, hail, snow, leaves and bird droppings. It weighs 5 pounds, so it is substantial without being unwieldy, and it folds down for storage between seasons.
Two details set it apart. The structured air vents on both sides cut condensation and stop the cover ballooning in wind, which matters more than it sounds, because a billowing cover catches air and pulls at its own anchor points. And the elastic draw cords plus plastic clips anchor to the wheel legs rather than the frame, which gives you a second, lower line of restraint.
What to check before you buy?
Measure the full width including both side shelves, not just the cooking surface. At 28 inches wide this suits a two-shelf station, and on a slimmer single-shelf griddle the cover will hang loose and pool water where the extra material sags.
Note the heat requirement too. You need to wait for the griddle to cool fully before fitting, which is a small inconvenience after a long cook and an easy mistake to make in a hurry.
Where it falls short?
The loose fit on a narrow griddle is a real downside rather than a technicality. Extra fabric hanging off the sides can hold water, and a sagging hem is exactly the failure mode that leaves edges of the cooking surface uncovered.
Only one color is shown for this 36 inch size. The brown finish does suit a wood or stone patio better than the usual black, but you have no alternative to compare it against.
9. Onlyfire Griddle Cover for Blackstone 36 inch – Best for RV and Tailgating
Pros
- 600D oxford with PVC coating holds up to sun
- rain
- snow and temperature swings
- Two reinforced straps lock under the frame for high wind or an RV
- Broad compatibility across Blackstone
- Camp Chef and Weber 4-burner units
- Folds down small for RV
- garage or bin storage
Cons
- Will not fit the Blackstone 36 inch ProSeries
- Plain all-black design with no color options
- Lowest review volume among the 36 inch covers here
Most of this roundup assumes a griddle that lives somewhere and gets covered. This one is built for a griddle that moves. The 600D heavy-duty oxford polyester with a water-resistant PVC coating handles the temperature swings of a tailgate or an RV storage bay, and it folds down small enough for a bin.
It measures 66.5 inches by 22.5 inches by 26 inches and is listed for Blackstone 1554, 1560, 1565, 1825, 1836, the 1819 charcoal combo, the 1868 air fryer, Camp Chef FTG600 and Weber 44310401. That compatibility list is the reason it earns this spot rather than a generic budget pick.
Fastening is two reinforced straps that lock under the griddle frame, which is the same under-frame anchor idea as the Blackstone OEM cover and considerably stronger than an elastic hem. Reinforced stitching handles the tear resistance, and the finish hoses clean easily.
Owners describe the material as standing up to sun, rain, snow and temperature swings, with useful multi-brand fit and straps that stay put. It is also among the least expensive 36 inch covers in the roundup, which makes the pair sensible if you cover two griddles.
What to check before you buy?
Confirm it is not the ProSeries. That exclusion comes up repeatedly in the reviews and in the listing, and a cover that is a few inches short at the top edge is the exact thing that lets water sit on the cooking surface.
Think about packed volume. This folds compactly, which is exactly what you want in an RV, and exactly what you do not need if your griddle sits on a patio, where the fold volume is storage you probably do not have.
Where it falls short?
It carries the lowest review volume among the 36 inch covers in this roundup at 2,868, and a lower sales rank in its category, so the long-term evidence base here is thinner than the leaders.
It is also a plain all-black design with no color options, and there are no vents. The under-frame straps do the work of keeping it on, but moisture management after a wet spell is entirely on you.
10. KINGLY 1000D Heavy Duty Griddle Cover – Best for Full Sun Exposure
Griddle Cover for Blackstone 36″ Griddle Compared to Blackstone 1528,1000D
Pros
- Heaviest fabric in the roundup at 1000D for tear and abrasion resistance
- Sealed double-stitching seam tape for genuine waterproofing
- UPF 50+ fabric slows fading
- aging and cracking
- Air vents release moisture and cut condensation
- Integrated handles for fitting
- hanging and storage
Cons
- Excludes the Blackstone ProSeries
- rangetop
- air fryer
- cabinet
- hooded and culinary models
- Velcro and strap adjustment takes effort on the first fit
- No storage pouch included
This is the fabric upgrade pick. Where most covers in this roundup use 600D polyester or oxford, this one uses 1000D tear-resistant Oxford fabric, which the listing puts at roughly twice the abrasion resistance of 420D and 600D constructions. For a griddle sitting in an unshaded patio, that is the number that matters most.
It measures 67 inches by 23 inches by 26 inches and fits the Blackstone 36 inch griddle, Camp Chef 600, Royal Gourmet 4-burner and similar 4-burner units. It carries a 4.7 average across 2,601 reviews, with 83 percent at five stars.
Two claims stand out. The first is UPF 50+ fabric blocking 99.99 percent of UV rays, which is the most specific UV rating any cover in this roundup carries and the reason it earns a place on a sun-exposed patio. The second is waterproof outer and inner layers with sealed double-stitching seam tape, which is genuine seam sealing rather than stitching alone.
It also has side air vents for circulation and anti-billow, plus lengthened and widened adjustable side straps and extra bottom straps. Owners respond to exactly the combination they respond to in a well-made cover: heavy fabric, sealed seams, and vents that let moisture out.
What to check before you buy?
The exclusion list here is the widest of any cover we looked at. It does not fit the Blackstone 36 inch ProSeries, rangetop, air fryer, cabinet, hooded or culinary griddles, and if you own a hooded 36 inch station this is the wrong cover.
Budget a few extra minutes for the first fit. The velcro and strap adjustment takes a little effort to get into position, and once it is set most owners say it stays put.
Where it falls short?
It is the only cover here with no storage pouch, so once you take it off you need somewhere to keep a full-size 1000D cover. That is manageable with the integrated handles, which let you hang it on a wall, but it is one more thing to plan for.
On fit precision, 23 inches wide is tighter than the vented options here, so a griddle with protruding side bars or a raised handle can crowd the seams. Measure before you order, because the fabric weight will not save a cover that does not close.
How to Choose a Griddle Cover for Outdoor Storage?
The best material for an outdoor grill cover is heavy polyester or Oxford cloth at 600D or above, with a water-resistant coating, reinforced or sealed seams, a UV-resistant finish, dual straps, and air vents. Below 600D you are buying a tarp, and at 1000D you are buying abrasion resistance you may not need unless the patio is fully unshaded.
Beyond material, six things decide whether a cover protects a griddle through a real winter.
Fabric weight. Denier measures fabric density. 210D and 420D constructions are thin and tear easily at the elbows, 600D is the practical floor for year-round outdoor storage, and 1000D is for exposed, unshaded patios. Five of the ten covers here use 600D or heavier.
Seam construction. Stitching alone is a leak path. Seam tape, hot-melt sealing, or full seam taping is what separates the covers that hold out driving rain from the ones that bead water on the surface. NettyPro and Unicook seal their seams; most others stitch.
UV resistance. UV exposure does not just fade fabric, it makes it brittle. Look for a stated UV treatment or a rating, and note that the lighter colorways in this category fade first, as owners of the brown NettyPro report after several seasons of full sun.
Fit. A cover that fits everything fits nothing perfectly. Model-specific covers like the Blackstone 5482 and 5483 hug the shape including a hood, while universal covers save you guessing but need you to measure. Measure length, width and height, and include side shelves and any attached tank in the width.
Wind security. Look for straps that anchor under the griddle base or frame, not just a buckle that catches the hem. Poly-resin buckles, plastic clips and draw cords that clip to the wheel legs are the three most reliable options in this roundup. A cover with only hook-and-loop needs re-strapping after a couple of seasons.
Ventilation. This is the one buyers skip and then blame the cover for. NettyPro, ULTCOVER and KINGLY all have vents, and they are the covers to favor if your griddle sits in shade or damp air. Without airflow, a sealed cover can hold moisture against the steel it was bought to protect.
Hard Cover vs. Soft Cover: Which One Do You Need?
For outdoor storage, a fabric cover is what protects the cooking surface, and every pick in this roundup is a fabric cover. A hard molded shell or a plywood box solves a different problem: physical impact, theft and the kind of wind that turns a fabric cover into a sail.
Forum owners of outdoor griddles consistently pair a hard lid with a fabric cover rather than choosing one or the other, and that pairing is the practical answer. The lid handles hail, branches and gusts while the fabric handles rain, UV, dust and bird droppings across the many months the lid is open.
A DIY plywood box with a lip is a genuinely good option for a fixed patio position, and owners build them because they double as counter space when the griddle is uncovered. The cost is losing mobility and having to build it to your exact footprint.
So the decision is simple. If your griddle stays in one spot and the weather there is severe, add a hard shell or a box over the top of one of the fabric covers here. If your griddle moves, or the weather is ordinary rain and sun, the fabric covers in this roundup are the right answer on their own.
Which Cover Size Fits Your Griddle?
Match the cover to the griddle’s overall footprint, not the burner count. Here is the sizing breakdown across the ten covers, from the smallest fit to the largest.
22 and 28 inch single-shelf griddles. The Unicook cover at 45 by 23 by 25 inches is the dedicated fit here, sized for the Blackstone 28 inch single-shelf griddle and Nexgrill equivalents. It does not fit the Blackstone 28 inch ProSeries or shelf models 1856 and 1924.
28 inch griddles with a hood. The Blackstone 5483 is purpose-built for that shape, with a generous fit that also covers the propane tank and front shelf. The ATHLEEGOUS line also offers a 28 inch with-hood size in the same fabric.
36 inch four-burner flat tops without a hood. This is the most crowded category. The Blackstone 36 inch cover, iCOVER, ATHLEEGOUS, NettyPro, Onlyfire and KINGLY all fit here, ranging from 65 by 22.5 by 26 inches up to 67 by 27 by 32 inches. All of them exclude the Blackstone 36 inch ProSeries.
36 inch griddles with a hood. The Blackstone 5482 is the dedicated fit, and ULTCOVER is the wide option at 67 by 28 by 32 inches for hooded two-shelf units. The KINGLY cover explicitly excludes hooded models, so check that list carefully.
Whatever the size, measure the unit yourself and include shelves and any attached propane tank in the width. Every fit problem in this category traces back to someone trusting a listing instead of a tape measure.
How to Stop a Cover from Blowing Away?
Covers blowing off in wind is the most common complaint owners post, and it is usually a fastening problem rather than a fabric problem. The covers in this roundup that use straps anchoring under the griddle base, which the Blackstone 36 inch cover, the ATHLEEGOUS and the Onlyfire all do, address it in hardware.
Beyond straps, four habits make the difference. Add weight on top of the cover, where bricks or pavers sit on the flat top section and on the corners but never on a hinge or a vent. Use a second set of straps, since owners on exposed patios run an extra strap around the frame rather than relying on the factory pair.
Anchor low, not just high. ULTCOVER clips its draw cords to the wheel legs, and that lower line of restraint is what stops a cover from peeling back at the hem where most failures start. Check the hem every month or two, because that is the first place a cover loosens.
And check the fit after the first storm. A cover that was snug when new will relax after a season of heat and cold, and a stretched strap does not recover. Re-tension anything that has gone slack before the next front moves through.
Where the Condensation Comes From and How to Stop It?
Condensation is the most underappreciated fact in this category: a sealed cover over a warm steel surface can be the thing that causes the rust it was bought to prevent. Warm day, cool night, and moisture already in the air condenses on the cooler surface underneath, then sits there under a sealed cover with nowhere to go.
That is the pattern behind the mold complaints owners describe, and behind the griddles that end up looking so rough that people discount them when they sell. Nobody blames the cover, because the cover was the reasonable purchase.
Three covers here handle it directly. NettyPro has a wide covered front vent, ULTCOVER has structured air vents at both sides that also stop billowing in wind, and KINGLY has side air vents for circulation and anti-billow. If your griddle sits in shade or damp air, those are the three to favor.
On the rest, the practical habits are what close the gap. Let the griddle cool fully before the cover goes on, air it out in sun for a while after a wet night before covering it, and wipe the surface dry rather than covering it damp. Check under the cover monthly in the first season, when you can still fix a problem instead of scrubbing one.
Re-Seasoning a Griddle After a Wet Winter
If a cover has already failed and you are looking at surface rust, the griddle is usually recoverable. This is the routine we would run, and it takes an afternoon.
Strip it. Scrape off the seasoning and rust with a stiff nylon brush or a wire brush, working with the grain of the steel. A 3M strip-and-flap pad works well for a surface with light orange bloom, and it takes a full surface stripping more than scrubbing does.
Rinse and dry completely. Wipe off residue with a damp paper towel, then dry the surface and heat it. Rust that keeps coming back is almost always moisture you missed rather than steel you missed.
Re-season. Apply a very thin layer of high smoke point oil, wipe it until the surface looks almost dry, and heat the griddle until it just starts to smoke. Repeat two or three times, letting the surface cool between coats. The polymerised oil layer is what keeps the next wet winter from starting the process over.
Then fix the storage problem. A re-seasoned griddle under the same non-vented cover in the same damp spot will go again. Move it, add a vented cover, or build a hard shell over the top before the next wet season.
One last storage habit worth naming: disconnect the propane tank and keep it upright and out of direct sun, rather than leaving it under a cover wrapped tightly around the griddle.
Frequently Asked Questions
What is the best griddle cover?
The best griddle cover for outdoor storage is a 600D or heavier polyester or Oxford cover with a water-resistant coating, reinforced or seam-taped stitching, straps that anchor under the griddle base, and air vents. Fabric weight sets durability, sealed seams stop leaks, under-frame straps stop wind lift, and vents stop the trapped condensation that causes surface rust.
Can you leave a Blackstone griddle outside with a cover?
Yes, with caveats. A cover rated for the correct model, paired with a hard lid or hood for hail and impact, keeps a griddle outside for years. Match the cover to the exact model, confirm ProSeries and hooded exclusions before buying, and choose a vented cover if your spot stays damp. The cover reduces weather exposure; it does not make the griddle maintenance-free.
What is the best material for an outdoor grill cover?
Heavy polyester or Oxford cloth at 600D or above. 600D is the practical floor for year-round outdoor storage, and 1000D adds abrasion resistance for fully unshaded patios. Look for a water-resistant coating, reinforced or seam-taped stitching, a stated UV treatment, and vents. Below 600D, expect tearing at the corners after a season or two.
What size griddle cover do I need?
Match the griddle’s overall footprint including side shelves and any attached propane tank. In this roundup, 45 by 23 by 25 inches fits 22 and 28 inch single-shelf griddles, 65 to 67 by 22.5 to 27 by 26 to 32 inches fits 36 inch four-burner flat tops, and dedicated covers fit hooded 28 inch and 36 inch stations. Measure before ordering.
Is it okay if my Blackstone gets rained on?
Occasional rain is fine. Cold-rolled steel handles a passing shower without lasting damage, especially with a hard lid closed. Trouble starts with repeated cycles of wet and dry, and with moisture trapped under a sealed cover, which is the pattern that produces surface rust. Let the griddle air out after heavy rain before covering it again.
Will a griddle cover blow away in the wind?
It can, if it relies on an elastic hem or hook-and-loop alone. Covers with straps that clip under the griddle base or frame, or draw cords that anchor to the wheel legs, hold far better. Add weight on the flat top section, run an extra strap around the frame, and re-tension any slack after the first storm.
The Verdict
The best griddle covers for outdoor storage all solve the same four problems: water getting in, sunlight getting to the fabric, wind getting under the hem, and moisture getting trapped against the steel. The Blackstone 36 inch cover wins this roundup on 600D fabric, under-base buckle straps and the highest 4.8 average among the most-reviewed picks, so its failure modes are the best documented in the category.
If you own a different brand or a different size, the principle is what matters. Buy 600D or heavier, insist on sealed seams, anchor under the frame rather than at the hem, and pick a vented model if your spot stays damp. Those four choices decide whether your griddle still looks good in 2026.
