2025 Contra Costa County, California Wildfires

A fire is listed here when it is located in Contra Costa County. Each complex is counted once, through its parent: the parent carries the complex's acres, and its member fires are listed beneath it without being counted again. A fire that crossed a county line is listed with the acres that burned in Contra Costa County, not its whole reported size. A fire located elsewhere that burned into Contra Costa County is listed too, at its Contra Costa County acres, and is not added to the Contra Costa County fire counts. County lines come from a different boundary dataset than state lines, so Contra Costa County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
