Hot, dry and windy weather can contribute to fire danger. Specifically, weather-related factors that contribute to an increased risk of bushfire danger include: High temperatures and Low humidity.
What two weather factors influence fire behavior the most?
In general, fuels will ignite more readily at high temperatures than at low temperatures. Humidity, the amount of water vapor in the air, affects the moisture level of a fuel. At low humidity levels, fuels become dry and, therefore, catch fire more easily and burn more quickly than when humidity levels are high
