Can You Leave Your Grill Outside All Winter?

Does Climate Affect Outdoor Grill Storage?

The climate where you live plays a major role in whether it’s feasible to leave your grill outside during winter. In regions with heavy snow, freezing temperatures, and constant moisture, grills are more susceptible to rust and weather damage. On the other hand, if you live in a mild climate where winter means occasional rain and cool breezes, your grill may handle the season with fewer issues.

As you consider storage options, consider these factors:

• Snow and Ice Accumulation: Metal grills exposed to snow or ice can corrode more quickly, particularly if they’re not made from stainless steel.
• Humidity Levels: In consistently damp areas, moisture can seep into small crevices, leading to rust.
• Wind: Strong winds can damage grill covers... and can even knock over lighter models.
• Location Matters: You'll want to place the grill on a level, elevated surface. This will reduce contact with standing water or snow.
• Avoid Direct Exposure: Store your grill in a sheltered spot, like under a patio roof or against a windbreak.
• Secure the Cover: Use straps or bungee cords to keep the cover in place during windy conditions.
• Don’t Forget the Tools: Store accessories like brushes, thermometers, and utensils indoors to avoid damage.

How to Winterize Gas and Charcoal Grills

Whether you have a Weber gas grill or a classic charcoal setup, it's a good idea to prepare your grill for being in outdoor storage during winter conditions:

• Give it a thorough cleaning. Grab a grill brush to scrub away food debris, clean the grease tray, and clean the ash catcher to prevent corrosion.
• Disconnect the propane tank. For gas grills, disconnect the propane tank and store the propane tank indoors like in the garage or a dry, ventilated area away from heat sources.
• Season the cooking grates. On charcoal grills, lightly coat grill grates with cooking oil to prevent rust.
• Invest in a grill cover. Choose a brand-specific custom cover or high-quality universal heavy-duty grill cover designed to fit your grill. Look for water-resistant materials that allow for some airflow to reduce condensation.
• Check for weak points. Inspect your grill for damage like cracks, loose components, or damaged gaskets. Address these issues before putting your grill in storage.

Are Pellet Grills Safe Outdoors All Winter?

Pellet grills like Traegers require extra attention during winter. These grills feature electronics that can be sensitive to extreme cold and moisture. If you live in an area with freezing temperatures, follow these steps to keep it functional:

1. Empty the Pellet Hopper: Remove unused pellets to prevent them from absorbing moisture and hardening inside the auger.
2. Clean the Burn Pot: Clear out ash and residue to avoid clogging.
3. Protect the Controller Panel: Use a cover that includes a weather-resistant panel guard to shield electronic controls.
4. Store Pellets Properly: Keep wood pellets in a sealed, moisture-proof container indoors.

If you use your pellet grill in the winter frequently, you'll also want to consider a thermal blanket designed for your grill model to maintain consistent cooking temperatures.

FAQ

What happens if I don’t clean my grill before winter?

Forgetting to clean your grill before winter storage can lead to long-term damage. Grease and food residue may attract pests like rodents or insects to your grill in winter, while moisture trapped in dirt or ash can encourage rust in the grates or grill body. When you pull the grill out in the spring, you may find it clogged, rusted, or worse—home to a critter. Taking time to clean it thoroughly now will save you trouble later.

Can I leave a Blackstone griddle outside in the snow?

You can... although it's not recommended. The flat top is made of steel and moisture is the enemy of steel. For me, proper storage would be under a patio roof or indoor storage in a garage or shed to reduce exposure. Moisture from snow or general winter weather can cause rust if the griddle isn’t properly maintained. To get the grill ready for storage, clean and season the griddle top, for extra protection, close the lid or put your hard cover on it. If you don't have a hard cover, consider a piece of plywood or other material to keep the soft cover from sticking to the flat top surface. Make sure to cover it with a water-resistant Blackstone cover or tarp making sure to strap it down so the cover doesn't blow away.

Will cold weather damage my Traeger grill’s electronics?

Traeger grills are built to withstand normal outdoor use, but extreme cold could slightly strain the electronic components. You might notice slower electronic ignition time and a darkened control panel. Use a grill cover designed for your model and store it in a wind-protected area. If you frequently grill in sub-freezing temperatures, investing in a Traeger thermal blanket can help maintain cooking performance and protect the internal components.

Can I grill in the winter if I use a gas or pellet grill?

Absolutely! Grilling in the winter is safe and enjoyable if you take a few precautions. Use extra fuel, as cold weather increases consumption. Clear snow from the grilling area and always ensure proper ventilation to prevent gas buildup. For pellet grills, keep the hopper dry and monitor the grill’s temperature closely.
