The 2026 Wyoming wildfires are a series of active wildfires currently ongoing in Wyoming.
"Wildfire season" in Wyoming typically occurs between June and September, but wildfires can occur as early as April and late as December. Peak time of fire season is normally in July and August. Wildfires in Wyoming are triggered by a dry climate, drought, grasses die and dry out, and times when dry thunderstorms are more common. Humidity levels, dryness of fuel, wind, and temperature also play a crucial role. Forests that have not had wildfires in recent years have more fire fuel, and trees killed by disease and insect infestation quickly dry up and become a prime fuel for wildfires.
