How to Keep Your Grill Cover From Blowing Off in Wind

You walk out after a windy night and the grill cover is halfway across the yard again. That's the problem, and learning how to secure a grill cover in wind comes down to three things: wind speed, grill weight, and the hardware your cover already has. Match all three and the cover stays put through entire storm seasons.

In our research across manufacturer fitment guides and aggregate user reports, loose hems start lifting at gusts around 25 mph, and unsecured covers routinely disappear above 40. Those thresholds matter because the right fix changes at each one. Here's the short version first, then the details.

Quick Answer: How to Keep a Grill Cover From Blowing Off

Cinch the cover hem tight, then anchor it with ball bungees. Hook each bungee through a metal grommet and onto the grill frame. Never anchor to the wheels or the ash catcher.

In gusts above 40 mph, anchor the grill itself or store it indoors. Drawstring covers only need a firm cinch and a tug test.

Your spot in the decision tree depends on conditions:

• Under 25 mph gusts: a snug elastic or drawstring hem usually holds on its own.
• 25 to 40 mph: add ball bungees or straps through grommets, attached to the frame.
• Above 40 mph or sustained gales: tie down the cover and anchor the grill, or move it into a shed.
• No grommets or straps at all: grip clips pinch the hem to the frame without any sewing.

What Changes the Fix: Wind Speed, Grill Weight, and Cover Hardware

Start with the wind, because it picks your method. The National Weather Service labels sustained winds of 25 to 31 mph a strong breeze and 39 to 46 mph a gale. A snug hem survives the first and loses the second.

Check gusts, not just the daily average. A calm 15 mph afternoon with 35 mph gusts will strip a cover that the average never hints at.

Next, weigh the risk. A 22-inch kettle grill runs roughly 45 to 50 pounds, and a cover turns it into a sail. Portables often sit under 30 pounds, and a hard gust can tip them outright.

Full-size carts are heavier, though tall hooded models and offset smokers catch more wind because of their stacks.

Cover fit classes track that size range. Covers marked 58 or 65 inches suit typical midsize gas grills, while 71 and 72 inch covers fit wide premium grills. Heavier, wider grills give the wind less leverage, but only when the cover itself is cinched.

Last, inventory what your cover already has:

• Metal grommets at the hem or corners
• A drawstring with a cord lock
• Velcro or buckle straps
• A plain elastic hem, and nothing else

If you've got grommets, ball bungees are the fastest win. If you've got nothing, grip clips solve it. If you've got Velcro straps that went limp after one summer, that's UV damage, and we'll cover replacements below.

Step-by-Step: Securing a Grill Cover in Wind

Work these five steps in order. The whole job takes about ten minutes.

Step 1: Fit the Cover Correctly Before You Fight the Wind

Pull the width, depth, and height from the published spec dimensions of your grill, then buy the fit class that clears all three. An oversized cover billows. An undersized one rides up and exposes corners.

Line up any built-in vents so air can pass through instead of inflating the fabric.

Step 2: Cinch the Hem Low, Below the Shelves and Above the Legs

Pull the hem down past the side shelves and cinch it above the legs. A low cinch kills the sail shape. If the cover has a drawstring, work the cord lock until the fabric hugs the firebox, then flatten deep folds.

Folds become flaps, and flaps become worn spots.

Step 3: Match the Fastener to What Your Cover Has

• Grommets: loop a ball bungee through each grommet and around the frame.
• Drawstring: cinch the cord lock, then add one bungee per rear leg for insurance.
• Buckle straps: clip and tighten until the webbing stops all wrinkles.
• Velcro: press the full length down, and expect to replace it yearly.
• Nothing: grip clips pinch the hem straight to the frame.

Keep tension moderate. You want the fabric snug, not drum-tight, because cold-weather shrinkage can tear corners stretched to their limit.

Step 4: Anchor to the Frame, Not the Wheels or the Ash Catcher

Hook every bungee to the cart frame, leg tubes, or bottom shelf. Wheels spin, ash catchers pop off, and either one dumps your setup the moment it moves. If the grill is brand new, finish the first burn-off cycle before strapping anything down, so fresh paint fumes don't bake into the cook box.

Step 5: The Tug Test and the First-Gust Check

Grab the hem and tug hard at three points. Nothing should lift, slide, or pop loose. Then walk out after the first real gust of the season and retension whatever slackened.

That one follow-up catches most failures before a storm does.

Ball Bungees vs Straps vs Clips vs Drawstrings: Which Fastener Actually Holds

Every method holds. Just not equally, and not in every climate.

Ball bungees beat hook bungees for one reason. The ball spreads load across the whole grommet, while a metal hook concentrates force on a single point and tears it out. Aggregate user reviews report the same failure pattern repeatedly: hooks rip grommets within a season, then gouge the painted lid on the way past.

Velcro is the weak link outdoors. UV radiation breaks down the hook-and-loop bond, and once it goes limp it never recovers. Buckle straps cost a few dollars more and take a minute longer, but they hold tension longer than anything else on the list.

As of 2026, a pack of 9-inch ball bungees runs about $10, and aftermarket strap kits sit in the $15 to $25 range. Apply a pre-purchase checklist before adding any of it: grommet spacing, strap length, and UV-rated webbing all decide whether the kit actually fits your cover.

When the Cover Isn't the Problem: Anchoring the Grill Itself

If gusts push past 40 mph, a perfectly strapped cover can still topple a light grill. The fabric catches wind like a sail and drags the whole unit with it. At that point the question shifts from the cover to the grill.

Work through the if/then:

• If the grill weighs under 50 pounds, treat 40 mph gusts as a tip risk. Lock the casters or chock the wheels with a brick.
• If it sits on an exposed balcony or deck, add ballast. A sandbag or paver across the lower shelf does more than any cover strap.
• If a sturdy post or railing sits within bungee reach, run a cord from the frame to it. Check building rules first, since some associations prohibit balcony grills entirely.

Position helps too. A corner where two walls meet, or the lee side of a fence, cuts wind load dramatically. Aim the grill's back panel into the prevailing wind, not the hood edge.

Keep placement rules in mind while you rearrange. NFPA fire-safety guidance calls for grills well clear of siding, eaves, and anything combustible, and a tempting windbreak is never a reason to tuck a grill against the house.

There's also a ceiling on all of this. If the forecast shows sustained gale-force wind for days, the right answer is the shed or the garage. A five-minute walk beats replacing a tipped grill.

Cover-Securing Mistakes That End in Torn Covers or Tipped Grills

Most failed setups trace back to one of these five errors. Each one has a cheap fix.

Covering a warm grill. Residual heat softens vinyl within minutes and can scorch fabric against a hot firebox. Manufacturer manuals consistently call for a full cool-down after the last burn, often 30 to 60 minutes, before any cover goes on. If you smell hot paint, the grill isn't ready.

Using hook bungees on grommets. A metal hook concentrates all the load on a single point of the grommet. When it tears free, it usually gouges the painted lid on the way past. If that's what you own, swap to ball-end cords before the next storm.

Re-securing mid-gust. A flapping cover with metal grommets can cut your hands, and gusts arrive in clusters. If the forecast shows sustained winds over 40 mph, let it flap and wait. Retension once the front clears.

Overtightening in summer. Elastic hems and webbing straps contract in cold weather. A drum-tight July fit can tear a corner seam by January. Leave enough slack that the fabric flexes when you press it.

Skipping the small stuff. Close the propane valve before covering. Dry the cover fully before storage, because trapped moisture feeds mildew and firebox rust. And shake it out each time you fit it, since a loose cover is the easiest winter nesting spot a mouse will ever find.

FAQs: Wind, Grill Covers, and What Actually Works

What Wind Speed Will Blow a Grill Cover Off?

Loose hems start lifting around 25 mph gusts, and unsecured covers routinely tear free above 40 mph. A snug drawstring or elastic hem usually survives the first range. Anything past the second calls for bungees, straps, and grill anchors.

Should You Even Cover a Grill in High Wind?

Yes, but only if it's fastened and the grill is completely cool. A loose cover in a gale becomes a projectile that can dent cars or crack windows. If securing isn't practical, pull the cover and store it until the wind dies down.

How Do You Secure a Cover With No Grommets or Straps?

Grip clips are the fastest answer. They pinch the hem fabric directly to the cart frame with no sewing required. Four clips, one per corner, handles most gusts under 40 mph.

An aftermarket grommet kit is the permanent upgrade.

Are Strapped Covers Worth the Extra Money?

For exposed or coastal sites, yes. Buckle straps hold tension longer than any other fastener and typically outlast three seasons of UV exposure. In sheltered yards with mild wind, a drawstring cover plus two ball bungees does the same job for less.

Can I Use a Tarp and Clips Instead of a Grill Cover?

You can, but not for long. Tarps aren't breathable, so trapped moisture accelerates rust and mildew on the firebox. A ventilated grill cover costs about the same as a decent tarp and clip set, and it's shaped to shed water properly.

How Do I Keep the Setup Working Season After Season?

Retension everything after the first big gust each season, since new fabric stretches. Wash the cover with mild soap each spring and dry it completely before storing. Inspect grommets and stitching yearly, and replace any strap that sun exposure has made brittle.
