Fire in Wet Conditions

When to use this

When rain has fallen in the last 24 hours or is falling now.

• Starting or maintaining a fire after rain
• Any trip in the Pacific Northwest, Southeast, or anywhere with afternoon showers
• Building the confidence to camp in shoulder season

What you need

• Dry tinder kept in a sealed bag or inside your jacket
• Fatwood or petroleum jelly-treated cotton balls
• A knife for shaving dry wood from the interior of logs
• A tarp or rain fly over the fire area (set up before you start)

Step by step

1. 1.Set up rain protection first. A tarp 8–10 feet above the fire ring, pitched at a steep angle to shed runoff, keeps your fire zone dry while you build.
2. 2.Never try to light surface-wet wood. Find a standing dead tree (not a fallen log — those are wet through) and shave dry wood from the interior with your knife.
3. 3.Build an elevated fire lay: put a dry log flat on the ground as a base platform, then build your tinder and kindling on top. Ground contact wicks moisture up into your tinder.
4. 4.Use your best tinder. Wet conditions are for petroleum-jelly cotton balls, not dry leaves you found nearby. Don't improvise tinder in the rain.
5. 5.Build a smaller fire structure than usual — a tight teepee or log-cabin rather than a large open structure. Small fires are easier to establish and maintain in wet conditions.
6. 6.Feed it slowly. Start with the smallest possible kindling and don't add large wood until you have a stable flame and a growing coal bed.

Pro tips

• Birch bark contains natural oils and lights readily even when surface-wet. If you find a fallen birch, peel the outer bark — the oil-rich layer underneath often stays dry.
• Carry a fire-starting kit with waterproof matches, a lighter, cotton balls, fatwood, and fire paste in a dry bag. This is not improvised at the campsite.

Common mistakes

• Trying to light wet wood with a single lighter flick and giving up when it doesn't catch. Wet conditions require more heat, held longer — a longer flame from a cotton ball, not a quick ignition.
• Building the fire on wet ground without a platform. Ground moisture climbs into the fuel and kills the fire from below.
