2021 Fire Year

The 2021 wildfire season in California experienced an unusually early start amid an ongoing drought and historically low rainfall and reservoir levels. In January 2021 alone, 297 fires burned 1,171 acres on nonfederal land, which is almost triple the number of fires and more than 20 times the acreage of the five-year average for January. In July, more than three times as many acres had burned compared to the previous year through that date, with drought, extreme heat, and reduced snowpack contributing to the severity of the fires. On August 18, 2021, the state of California was facing "unprecedented fire conditions" as multiple fires including the Dixie Fire, McFarland Fire, Caldor Fire, and others raged on. In October, the state of California, especially in the Northern regions where most of the fires were located, received its first rain in over 200 days reducing the wildfire risk for much of the state.

Pictured: The Dixie Fire, which began in the Feather River Canyon and burned 963k acres in July of 2021.
