Quick Answer
Wet weather is most likely to hinder fire making when relative humidity is above 80% and the air temperature is below 50°F (10°C).
Understanding Fire Dampness
When the air is saturated with moisture, the fire’s ability to draw oxygen is severely impaired. In these conditions, it’s essential to understand that fire needs a specific balance of oxygen, heat, and fuel to sustain itself. If the air is too wet, the fire will struggle to draw oxygen, leading to a slow and difficult burn.
Techniques for Fire Starting in Wet Conditions
One technique for starting a fire in wet conditions is to create a “fire bed” using tinder, kindling, and fuel. This involves arranging the materials in a specific order, with tinder (e.g., dry leaves, grass, or small twigs) at the bottom, kindling (e.g., sticks and small branches) in the middle, and fuel (e.g., larger logs) on top. When starting the fire, use a high-temperature ignition source, such as a lighter or ferrocerium rod, to generate heat quickly. This technique allows for a rapid buildup of heat, which can help to evaporate moisture from the surrounding air, creating a more favorable environment for the fire to start and sustain itself.
Fire Starting Tools and Strategies
When fire starting in wet conditions, it’s crucial to have the right tools and strategies at your disposal. A ferrocerium rod, for example, can produce a high-temperature spark, even in damp conditions. This can be used to ignite tinder and kindling, creating a fire that can eventually burn through the surrounding moisture. Additionally, using a firesteel or other high-temperature ignition source can be effective in wet conditions. It’s also essential to note that the type of fuel used can affect the fire’s ability to start and sustain itself in wet conditions. Damp wood, for example, is much harder to ignite than dry wood, so it’s essential to have a reliable source of dry fuel to use in conjunction with a high-temperature ignition source.
