The two most critical aspects of weather that influence a wildland fire are moisture and:

In the context of wildland fire behavior, wind is indeed a critical factor alongside moisture content. Wind can significantly impact the rate and direction of fire spread. It influences how quickly a fire can grow; for instance, strong winds can carry embers to new locations, igniting spot fires ahead of the main fire. Wind can also intensify the fire by providing additional oxygen and elevating temperatures in the vicinity of the flames, making it easier for the fire to spread.

Moisture content in vegetation, combined with wind conditions, is vital for understanding the potential for fire ignition and spread. High winds can dry out moist vegetation more quickly, making it more susceptible to burning. Therefore, when evaluating fire risk in wildland areas, considering both moisture and wind is essential for effective fire management and safety planning.
