Cooking in Wind, Cold and Rain on a Collapsible Grill
How wind, cold and wet weather change a charcoal fire in an open flat pack grill and what to do about each.
An open firebox is more exposed to weather than a lidded cooker. The fix is mostly planning.
| Condition | Effect | What to do |
|---|---|---|
| Wind | Coals burn hot and fast on the windward side; sparks and ash blow | Shelter the grill (with safe clearance), point the coal end into the wind, use more fuel, skip cooking in high wind or red-flag conditions |
| Cold | Food and steel soak up heat; slower cooks | More charcoal, keep coals together, trust the thermometer |
| Rain | Hard to light, coals weaken | Keep charcoal dry in a lidded bin; cook in the open, never under a tent, awning or roof; dry and oil the grill after |
| Hot, dry weather | Spark risk | Check burn bans, clear the area, keep water at hand |
Never move the fire indoors
Burning charcoal produces carbon monoxide. Never use a charcoal grill inside a tent, camper, garage, vehicle, boat cabin or any enclosed space, even to get out of the rain.
After a wet cook
Carbon steel left wet will rust. Dry the grill (a warm grill dries itself quickly), wipe on a thin coat of oil, and store it dry. See surface rust.
Fire safety on any collapsible grill
- Outdoors only. Burning charcoal makes carbon monoxide, which you can't see or smell. Never use it in a garage, tent, camper, vehicle, boat cabin or under a roof or awning.
- Non-combustible, level ground. Soil, gravel, sand, concrete, pavers or a fire-safe pad.
- Clearance. Away from walls, vehicles, tents, overhanging branches and dry grass. Kids and pets kept back.
- Seated tabs. Check every tab is fully in its slot before you add fuel.
- Water and gloves at hand. Hot steel looks exactly like cold steel.
- Leave it alone until cold. Don't move or take apart a lit or warm grill.
Mistakes new flat pack owners make
- Too much charcoal. A small firebox gets very hot. Start with half a chimney and add.
- No cool zone. Without an empty end, a flare-up has nowhere to go.
- Cooking on black coals. Wait for gray ash.
- Old ash left in. It blocks airflow; empty it before every cook.
- Heavy oil when seasoning. Thin coats cure; thick coats turn gummy.
- Packing it warm. Wait until steel and ash are cold, every time.
The one-minute care habit
Most carbon steel problems come from skipping the last minute of a cook. After the grill cools, scrape the grates, empty the ash, and wipe a whisper-thin coat of oil or Seasoning Balm on the cooking surfaces. Store it dry. That habit is the difference between a grill that darkens into a slick patina and one that shows orange freckles every spring. If freckles do show up, it's not a disaster: see surface rust.
Questions people ask
Can I use a charcoal grill under a tent or awning in the rain?
No. Charcoal produces carbon monoxide and the fire is a hazard. Cook in the open.
