How to Pick a Grill Cover That Survives Wind and Rain
Weber’s 7130 Premium Grill Cover fits Genesis II models exactly and uses heavy fabric that holds up through seasons outdoors. UNICOOK’s Heavy Duty Waterproof Grill Cover suits most other grills. Classic Accessories’ Ravenna adds padding and a more finished look for anyone who wants both.
Weber’s 7130 Premium Grill Cover is the right call for anyone with a matching Genesis II grill. UNICOOK’s Heavy Duty Waterproof Grill Cover fits the widest range of other grills. Classic Accessories’ Ravenna wins on padding and appearance.
Nearly every listing claims waterproof and heavy duty, yet covers still fail at predictable points within two seasons: seam tape peels, fabric fades and cracks under UV, and wind lifts a loose cover clean off the grill. We compared fabric weights, coating types, vent placement, and strap systems, then weighed what owners report after a year or more outdoors.
Our top picks
Weber 7130 Premium Grill Cover
Built specifically for the Genesis II three burner range, so it sits snugly instead of billowing like a generic sheet. Heavy polyester fabric shrugs off rain and sun, and side straps with clips keep it anchored through gusts. Model-specific sizing is both its strength and its limit.
Pros
- Tailored fit stops wind from lifting it
- Heavy fabric resists tearing near the handles
- Straps hold firm through gusty weather
Cons
- Fits only the specified Weber models
- Lacks a padded lining for cart edges
UNICOOK Heavy Duty Waterproof Grill Cover
Owners without a branded option usually land here first. Thick fabric pairs a waterproof PVC backing with a UV resistant outer layer, and handles and straps sit in the right spots. Sizing generously beats sizing tight, since the shape runs generic rather than model specific.
Pros
- Fits a wide range of grill sizes
- Side vents cut down on trapped condensation
- Reinforced handles make removal easy
Cons
- Generic shape leaves slack on smaller grills
- Weighs more than lightweight covers
Classic Accessories Ravenna Grill Cover
Woven outer fabric, padded handles, and an interior lining set this apart visually from plain polyester covers. The lining protects the grill lid finish from scuffs, and elastic hems paired with click-close straps keep it snug. Premium fabric explains both the look and the higher cost.
Pros
- Interior lining protects the lid’s finish
- Padded handles feel comfortable to grip
- Looks more like furniture than a tarp
Cons
- Water resistant rather than fully sealed
- Costs more than plain polyester covers
Char-Broil All-Season Grill Cover
Sized around Char-Broil’s own dimensions, removing the sizing guesswork for owners of that brand. Mid weight fabric carries a water resistant finish, and bottom ties cinch the hem down. Nothing here surprises, and that consistency is the appeal.
Pros
- Matches Char-Broil dimensions precisely
- Bottom ties stop the hem from flapping
- Slides on and off with little effort
Cons
- Thinner fabric than premium covers
- Water resistant rather than fully waterproof
SHINESTAR Grill Cover
Thick fabric and welded seams show up here at a price below the branded options, a rare pairing. Straps, handles, and vents are all present and functional. Owners report sizing runs generous, so measuring the grill including side shelves avoids a loose fit.
Pros
- Thick fabric for the price point
- Welded seams hold up better than stitching alone
- Buckle straps resist wind better than elastic
Cons
- Generous sizing leaves slack on smaller grills
- Stiffens in cold weather, making winter fitting awkward
Traeger Full-Length Grill Cover
Pellet grills expose a hopper and control panel that standard covers leave uncovered, and this one is cut to enclose both. Coverage runs full length down to the legs, shielding electronics from driving rain. Model-specific hopper cutouts mean it only fits listed Traeger sizes.
Pros
- Encloses the hopper and control panel
- Full length coverage protects legs and casters
- Cut specifically for pellet grill shapes
Cons
- Fits listed Traeger models only
- Elastic hem alone can lift in strong wind
Blackstone 5482 Griddle Cover
Griddles carry a wide flat top and side shelves that a domed grill cover cannot sit over properly. This one is cut for the 36 inch Blackstone and includes a strap against wind lift. Rust prevention drives the purchase, so fit matters more than fabric luxury here.
Pros
- Shaped correctly for a flat top griddle
- Strap keeps wind from lifting it
- Covers side shelves that domed covers miss
Cons
- Fits one griddle size only
- Lacks a padded lining
How to pick the right one
Measuring width, depth, and height with the shelves folded Skipping the folded side shelves is the most common sizing mistake, since they add several inches of width. Measure everything in its stored position, then size up rather than down. A cover that will not close at the bottom leaves the cart and legs exposed to the water you meant to block.
Why grill covers need vents, not just a seal A fully sealed cover traps moisture that evaporates off a warm grill and off the ground beneath it. That trapped humidity causes more corrosion than open air ever would. Side vents or mesh panels near the top let moisture escape. Covers without any venting are where owners most often report mold on the fabric and rust underneath.
How fabric weight and UV coating decide lifespan Denier ratings like 600D describe fabric thickness, and heavier fabric resists tearing at stress points such as the handles. UV coating matters just as much, since sunlight is what makes cheap covers turn brittle and crack at the folds. A cover sitting in constant sun needs both properties, while one under a porch roof can get by with less.
Straps hold up better than elastic in wind Elastic hems fit quickly and suit a sheltered patio well enough. Exposed locations call for buckled straps that cinch under the grill cart, since those keep the cover on the grill rather than in a neighbor’s yard. A cover with only elastic can still work in gusty spots if paired with a couple of aftermarket straps or bungee cords.

Common questions
Should you cover a grill while it’s still warm?
No. Let the grill cool completely first, since a hot lid can melt or scorch synthetic fabric and trapped heat breeds condensation inside the cover. Gas grills usually need about an hour after the burners go off, and charcoal grills need longer for embers to die out.
Do grill covers cause rust?
A vented cover on a dry, cool grill actually protects against rust. Problems start when a sealed cover traps moisture against a damp or still-warm grill. Trapped humidity is the real cause, which is why venting shows up on nearly every quality cover.
How long does a grill cover typically last?
Owners commonly report two to four seasons from a mid weight cover left in full sun, and longer under a porch or awning. Heavier fabric with real UV coating stretches that further. Seams and handle stress points usually fail before the main panel does.
Is a brand-specific cover better than a universal one?
A cover made for your exact grill model is usually worth choosing, since a tailored fit cuts down on wind lift and leaves less room for water to pool. Universal covers make more sense for older grills, discontinued models, or unusual footprints.
Can you wash a grill cover?
Hose it down and wipe with mild soapy water, then let it dry fully before refitting it. Skip the washing machine and pressure washer, since both can strip the waterproof backing. A coated cover should never go in a tumble dryer.
What’s different about covering a grill in winter?
A heavy cover is the baseline, and in snowy regions it helps to angle the lid or brush off snow rather than letting weight build up. Gas grills stored outside should have the propane tank disconnected and stored upright separately. Clean the grill thoroughly before the cover goes on for the season.
Do pellet grills need a different kind of cover?
Yes, since the hopper and control board extend beyond a standard grill silhouette and both need protection from rain. A cover cut specifically for pellet grills, like the Traeger full length option, encloses the hopper instead of leaving a gap at one end.
Will a grill cover keep animals away?
It helps, but a determined rodent can still chew through polyester. Cleaning grease traps and drip pans thoroughly matters more, since food residue is what attracts wildlife in the first place. A clean grill under a cover draws far less interest than a greasy one.
What size grill cover fits a Weber Genesis II?
Weber’s 7130 Premium Grill Cover is built specifically for the Genesis II three burner range and fits without the slack a universal cover leaves. Checking your exact Genesis II model against Weber’s sizing chart avoids ordering the wrong length.
Universal grill cover versus a brand-specific one: which fits better?
A brand-specific cover like Weber’s 7130 fits tighter and resists wind lift better. A universal option like UNICOOK’s Heavy Duty cover works when no branded cover exists, though it needs generous sizing to avoid a loose fit.
Our take
Weber owners get the best fit from the 7130 Premium Grill Cover, since a tailored shape solves the wind lift problem that ends most covers early. Everyone else should lean on UNICOOK’s Heavy Duty Waterproof Grill Cover for reliable universal coverage. Classic Accessories’ Ravenna earns its higher cost if padding and appearance matter as much as protection.
