The 2025 Oregon wildfire season was a series of wildfires that burned throughout the U.S. state of Oregon.
On May 7, Governor Tina Kotek signed a declaration declaring May âÂÂWildfire Awareness MonthâÂÂ. The season is expected to be similarly destructive as the 2024 season, the most destructive in history. On May 27, Senator Ron Wyden criticized cuts to NOAA under the second presidency of Donald Trump and other federal firefighting resources like the Forest Service, framing the agencies as nonpartisan and the cuts as not warranted. The Oregon Department of Forestry (ODF) set the start date for the season as June 1, but forecasts showed unseasonably hot and dry weather could start fires before the date.
By season end, Oregon wildfires burned 338,551 acres in 2025, which was under the 10-year average, and much less than the 2024 Oregon wildfire season. While acreage was much lower compared to recent years, over 205 structures were lost to wildfires in Oregon in 2025.
"Fire season" in Oregon typically begins in mid-May and ends with the first rains that normally begins in late September. Drought, snowpack levels, and local weather conditions play a role in Oregon's fire season, particularly in Eastern and Southwest Oregon. During peak fire season from July to September, most wildfires are caused by lightning, while ignitions in the early and later parts of the season are related to humans. Warm, dry conditions in summer heighten the wildfire risk. After over 100 years of fire suppression and prevention of all fires, there is now an abundance of fuel. Climate change is leading to a reduced snowpack with an earlier and reduced snowmelt, so there is a higher risk for areas that receive wildfires.
