What Changes When You Grill in Cold or Windy Weather

Grilling doesn’t have to stop when the weather turns. A gas grill will happily run through autumn, winter, and windy coastal evenings — but cold and wind do change a few things about how your grill behaves, and it’s worth knowing what to expect before you fire it up on a chilly night.

Here’s what actually changes, and how to adjust for it.

Wind Affects the Flame More Than You’d Think

Wind is the bigger factor of the two, and it affects gas grills in a very direct way: it can push the flame around, blow out a burner altogether, or create uneven heat across the plate if it’s hitting one side harder than the other.

What to do:

• Position the grill with its back or a solid side facing into the wind, rather than the open front.
• A stainless steel shield fitted to the side of the grill is designed for exactly this situation. It blocks gusts from disturbing the flame and also helps contain grease splatter, without you needing to relocate the whole grill. These are matched to each grill line, so it’s worth checking which shield fits your specific model.
• Keep the lid down as much as possible. Every time it’s open, wind has direct access to the flame and the plate loses heat faster than usual.
• If a burner does blow out, turn off the gas completely and wait a moment before relighting, rather than trying to reignite immediately.

Cold Temperatures Slow Down Preheating

In cold weather, two things work against you: the metal grill body and plate start from a colder baseline, and gas itself performs slightly differently in low temperatures. Propane in particular vaporises more slowly as it gets colder, which can mean slightly reduced pressure from the cylinder.

What to do:

• Give the grill extra preheat time — where 10–15 minutes is normal in summer, allow closer to 15–20 minutes in cold conditions.
• Keep the gas cylinder itself somewhere reasonably sheltered (not freezing cold, not near direct heat) rather than left out in open, exposed cold air, since very low cylinder temperatures are the main reason performance drops.
• Don’t judge readiness by how the grill looks or feels from the outside — a cold-weather preheat can look complete on the surface while the plate is still a few degrees short of proper cooking temperature. A quick water-drop test is a more reliable check than guessing by eye.

Heat Loss Adds Up Faster With the Lid Open

Opening the lid always loses some heat, but in cold or windy weather that heat escapes faster and takes longer to recover. If you’re used to checking food frequently, this is the habit most worth adjusting seasonally.

What to do:

• Check food less often, and rely more on timing and a thermometer than repeated lid-lifting.
• If you do need to check something, close the lid again quickly rather than leaving it propped open while you decide what to do next.

Food Behaves a Little Differently Too

Food coming straight from a cold fridge or freezer in winter starts even colder relative to the air temperature than it would in summer, which means it can take slightly longer to cook through, even once the plate itself is properly preheated.

What to do:

• Where possible, let food sit out briefly to take some of the chill off before it goes on the grill — this matters more in winter than people expect.
• Build in a little extra time when planning a cold-weather cook, especially for thicker cuts of meat.

Grease Behaves Differently in Cold Air Too

Grease and fat solidify much faster once they hit cold air, which means drainage channels and grease trays can clog or harden more quickly in winter than in warm weather.

What to do:

• Clean the grease tray and drainage path a little more often during cold-weather use, and do it while everything is still warm rather than letting fat set hard in the cold.

A Few Extra Winter and Windy-Weather Habits

• Give yourself more light. Shorter days mean more evening grilling in the dark — make sure the area around the grill is well lit, especially near the controls and gas connections.
• Handle metal parts with care. Grill housings and handles get cold to the touch in winter, and combined with sudden heat from the burners, it’s worth using grilling gloves rather than bare hands when adjusting anything.
• Check gas connections before each use. Cold weather can make rubber seals and hoses slightly less flexible, so it’s worth a quick visual check before lighting up, particularly after the grill has been stored outdoors through a cold spell.
• Cover the grill properly between uses. Wind-driven rain or snow finds its way into gaps a still, calm day wouldn’t expose — a properly fitted cover matters more in winter than in summer.

Grilling Isn’t Just a Summer Activity

None of this means cold or windy weather should keep the grill in storage. A well-built gas grill is designed to perform in more than ideal, calm summer conditions — you just need to preheat a little longer, shield the flame from wind, and expect food to take slightly more time than it would on a warm July evening.

Once you’ve adjusted for these few things, there’s no real reason to put the grill away until spring.
