How to build a fire in any condition
Can you build a fire in the rain? There's something primal about fire. It warms you, cooks your food, purifies your water, signals for help, and keeps the darkness at bay. But building one when conditions are against you — wet wood, howling wind, cold fingers, fading light — is a skill that separates confident adventurers from uncomfortable ones.
This guide is for the whole Roamrgear community: hikers, trail runners, campers, overlanders, and anyone who spends time in the South African outdoors. Read it, practise it, and make sure your kit is ready before you head out.
The Golden Rule: Preparation Beats Luck
The biggest mistake people make is trying to build a fire when they need one most — cold, wet, and exhausted. The best time to prepare is before you leave home.
Your fire kit should always include:
- A reliable fire starter (flint and steel or ferrocerium rod)
- Waterproof matches as a backup
- A lighter as a third backup
- Dry tinder stored in a zip-lock bag
- A small candle or fire starter tab for stubborn conditions
🔗 Roamrgear tip: The 6-in-1 Survival Paracord Watch has a built-in fire starter and flint & steel right on your wrist — your last line of defence when everything else gets wet.
Step 1: Choose Your Site Wisely
Before you touch a single stick, pick the right spot.
- Shelter from wind — use a rock face, a ridge, or dense bush as a natural windbreak. Wind is your fire's biggest enemy in the early stages.
- Dry ground — avoid building on wet soil or grass. If the ground is damp, build on a platform of bark or flat rocks.
- Clear overhead space — never build under low branches. Sparks travel further than you think.
- Away from your tent — at least 3 metres. A stray ember can destroy your shelter in seconds.
In South Africa, always check local fire regulations — many parks and reserves have fire bans in place, especially during dry season. Never build an open fire during a fire ban.
Step 2: Gather Your Three Fuel Types
Every fire needs three types of fuel, and you need all three before you light anything.
Tinder
This is what catches the first spark. It needs to be bone dry and ultra-fine.
- Dry grass, leaves, or bark shavings
- Thin strips of dry paper
- Cotton wool or dryer lint (carry some from home)
- Dead pine needles
- The inside of a dry bird's nest
Wet conditions tip: Look under rocks, inside hollow logs, and in sheltered nooks for dry tinder. Even in heavy rain, protected spots stay dry.
Kindling
Small sticks and twigs that catch from your tinder and build the fire's base heat. Thumb-thickness and smaller. Snap them — if they crack, they're dry enough.
Fuel Wood
Larger logs and branches that sustain your fire once it's established. In SA bush, hardwoods like rooikrans and Port Jackson burn long and hot. Avoid green wood — it smokes and smothers.
Step 3: Build Your Fire Structure
There are several structures that work well. Here are the two most useful for SA conditions:
The Teepee (Best for getting a fire going fast)
- Place a ball of tinder in the centre of your fire site
- Lean small kindling sticks over it in a teepee shape, leaving a gap on the windward side to feed oxygen
- Add a second layer of larger kindling around the first
- Light the tinder through the gap
- As it catches, add fuel wood in the same teepee shape
The Log Cabin (Best for sustained heat and cooking)
- Place two large fuel logs parallel to each other with tinder and kindling between them
- Stack two more logs across the top, perpendicular
- Continue building upwards like a log cabin
- Light the tinder at the base — the structure feeds itself as it burns down
Step 4: Light It
This is where most people struggle — especially in wind, rain, or cold.
With a flint and ferro rod:
- Hold the rod close to your tinder bundle
- Strike down firmly and consistently — angle the sparks directly into the tinder
- Shield the tinder with your body from wind
- Once it catches, blow gently and steadily at the base
With waterproof matches:
- Strike away from the wind
- Cup your hand immediately around the flame
- Touch it to the base of your tinder before the match head burns down
In wet conditions:
- Use a fire starter tab or small candle under your tinder — it burns long enough to dry out slightly damp material
- Build a platform of dry bark first to keep the tinder off wet ground
🔗 Roamrgear tip: Never rely on a single ignition source. Pair the 6-in-1 Survival Watch with the Silva Smini Headlamp for night fire-building — and always carry waterproof matches as a backup.
Step 5: Feed and Maintain It
Once your fire is going, the job isn't done.
- Add fuel gradually — smothering a young fire with big logs kills it. Build it up slowly.
- Feed from the sides, not the top — push logs inward as they burn rather than dropping new ones from above
- Keep it going in rain — build a small shelter over the fire using green branches or a tarp corner, keeping the shelter well away from the flames
- In wind — build a rock wall on the windward side to protect the flame
How to Build a Fire in Specific Conditions
Wet and Rainy
The key is elevation and shelter. Get your tinder off the wet ground using bark or flat stones. Find the driest tinder you can — inside a jacket pocket works. Use a fire starter tab to generate sustained heat that dries the wood as it burns.
High Wind
Wind can be your friend or your enemy. Build a rock or log windbreak on three sides, leaving the downwind side open for oxygen flow. Use the teepee structure — it self-feeds from the draft. Never fight a strong wind — reposition your site.
Cold and High Altitude
Cold numbs fingers and slows reaction times. Pack your fire kit where you can reach it with gloves on. A ferrocerium rod works in extreme cold where lighters often fail. Build your fire in a hollow or depression to retain heat.
Minimal Fuel Available
In dry or rocky terrain, fuel is scarce. Use the star fire method — lay 4–5 long logs radiating outward from a central fire like a star. Push them inward as they burn. This stretches a small fuel supply significantly.
Extinguishing Your Fire — Leave No Trace
A dead fire is not a safe fire unless it's cold to the touch.
- Let the wood burn completely to ash where possible
- Pour water over the fire — more than you think you need
- Stir the ash and embers with a stick, exposing any hidden hot spots
- Pour more water
- Press the back of your hand near the ash — if you feel heat, it's not out
- Scatter cold ash widely so no concentration of heat remains
Never leave a fire unattended. Never.

Final Word from the Roamrgear Community
Fire is not a luxury in the outdoors — it's a survival tool. The ability to build one confidently, in any weather, in any terrain, is one of the most valuable skills any South African adventurer can develop.
Practise at home before you need it in the field. Get your kit right. And when you're out there — in the Cederberg, the Drakensberg, the Lowveld, or wherever the trail takes you — you'll know you're ready for whatever comes.
