Quick Answer
Yes, you can safely ignite a fire under a shelter during rain, but it requires the right materials and techniques.
Choosing the Right Materials
Igniting a fire under a shelter during rain requires a reliable fire starter, adequate tinder, and protected matches or a lighter. Opt for materials that can withstand wet conditions, such as dryer lint, small twigs, or shredded newspaper. Avoid using damp or wet materials, as they will not burn efficiently. For example, you can use 1-2 handfuls of dryer lint as tinder, which can be easily ignited with a match or lighter.
Creating a Dry Zone
To create a dry zone under the shelter, use a tarp or plastic sheet to divert rainwater away from the area. You can also use rocks, logs, or other natural features to create a rain shadow. This will help keep the area dry and allow you to build a fire. For example, you can use a tarp to cover a 2x2 foot area, creating a dry zone where you can build your fire.
Building a Fire in Wet Conditions
When building a fire in wet conditions, start with a small fire pit or ring to contain the flames. Use a fire starter, such as a firesteel or a magnifying glass, to ignite your tinder. Once the tinder is burning well, add small twigs and sticks to the fire, gradually increasing the size of the material as the fire grows. To maintain the fire, keep the area around the fire dry and clear of debris. For example, use 2-3 small twigs as kindling, spaced evenly apart, to help the fire grow.
