California wildfire map today
Active wildfires in California right now, the fire-hazard classifications that cover the state, and where to find official information. The list and counts come from the national federal feed; the hazard classifications come from CAL FIRE. Both update on their own schedules — the active-fire data refreshes every 15 minutes.

What classifications cover California
The wildland-urban interface is the parts of the country where houses sit close enough to forest, brush, or grassland that wildfires can reach them. The national map of these areas, or WUI, is maintained by the SILVIS Lab at the University of Wisconsin–Madison. It marks a place as either inside or outside the interface; there are no severity grades.
California also publishes its own fire-hazard map, which grades land as Moderate, High, or Very High. CAL FIRE produces it through a state program called the Fire and Resource Assessment Program, or FRAP, and the map covers California only. No other state publishes an equivalent graded version.
CAL FIRE distinguishes fire hazard (the physical conditions that make wildfire possible) from fire risk (the potential for damage) — these zones map hazard, not risk.
Homes in the wildland-urban interface
About 35% of California’s homes sit inside the wildland-urban interface — roughly 5.1 million of 14.4 million statewide, according to the SILVIS Lab’s 2020 dataset. The share varies sharply by county: heavily urbanized counties hold the largest absolute counts, while rural mountain counties have higher percentages.
The five California counties with the most homes in the wildland-urban interface:
- Los Angeles County
- Riverside County
- San Diego County
- San Bernardino County
- Contra Costa County
Being in the interface is a description of geography, not a forecast of fire — it captures how close a building sits to vegetation that can burn. These classifications change slowly; the figures here come from the SILVIS Lab’s most recent revision of the 1990–2020 dataset, released February 2025.
Fire hazard severity zones
California’s fire hazard severity zones come in two maps, divided by who is responsible for fire protection in each area. The State Responsibility Area, or SRA, covers rural and unincorporated land that CAL FIRE protects directly. The current SRA zone map took effect on April 1, 2024.
The Local Responsibility Area, or LRA, covers incorporated cities and some special districts, where local fire departments take the lead. CAL FIRE publishes a recommended LRA zone map; the current version was released on March 24, 2025, and local governments adopt it into their building codes.
