This article is a summary of the 2023 Oregon wildfire season, comprising the series of significant wildfires that have burned in the U.S. state of Oregon since the beginning of the calendar year. Fire season officially began in all areas of the state by July 1, according to the Oregon Department of Forestry (ODF). As of September 5, 2023[update], the state had recorded 1,731 fires, which had burned a total of 159,991 acres (64,746 hectares).[1]
Outlook
Fire season in the Pacific Northwest often lasts from May until October.[2] The National Interagency Coordination Center, in its seasonal fire assessment and outlook released in July, forecast above-normal significant fire potential in the Pacific Northwest through September.[3] The August outlook continued this forecast, predicting that "Significant fire potential will be above average for the entire geographic area in August and September. In October, elevated risk of significant fires will shift west of the Cascades due to the likelihood of dry easterly winds in autumn. By November, significant fire risk will decrease back to normal (i.e., low) for the entire geographic area as cooler and wetter weather arrives."[4]: 6
All Oregon Department of Forestry districts declared the beginning of fire season by July 1.[5] The Northwest Coordination Center upgraded the region's preparedness level (referring to the availability of firefighting resources) from PL 1 to PL 2 on July 3, PL 3 on July 23, PL 4 on August 12, and PL5—the highest level—on August 19.[6]
