A series of wildfires burned throughout the U.S. state of Utah during 2023.
While the typical wildfire season in Utah varies, most fires occur in between July and October. Fire conditions can heavily depend on monsoons that last from late June to September. Dry monsoons can allow fires to start and spread easier, while wet ones can cause fire relief. Additionally, hot temperatures and overall dry conditions play a large role.
Concerns for a destructive fire season began after Utah's snowpack reached and began melting in spring. However, the start of fire season was late due to high fuel moistures from the snowpack. The El Niño prolonged cool, moist conditions from May through early July. Hot and dry conditions minimally increased fire activity in late July and early August, but was still well below average. Precipitation increased later in August (when 60% of Utah's summer precipitation occurred that year), coming when most vegetation began drying up. Additionally, the temperature that season was the lowest in Utah since 2014, 1.5 ðF above the 20th century average. Heavy rains in September effectively brought an end to fire season.
