2026 San Mateo County, California Wildfires

All 2026 San Mateo County Fires

A fire is listed here when it is located in San Mateo 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 San Mateo County, not its whole reported size. A fire located elsewhere that burned into San Mateo County is listed too, at its San Mateo County acres, and is not added to the San Mateo County fire counts. County lines come from a different boundary dataset than state lines, so San Mateo County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.

No fires are tracked in San Mateo County for the 2026 season. This table lists every fire the season statistics count for San Mateo County; for 2026 that list is empty. Statistics update with each data-update cycle, which normally runs about every 5 minutes.
