California Wildfires Today & Real-Time Satellite Telemetry
The California wildfire map delivers live, 24/7 tracking of active fires in California today, charting thermal hotspot anomalies, containment perimeters, and emergency evacuation notices across Northern California, the Central Valley, the Sierra Nevada, and Southern California (SoCal). Integrating near-real-time NASA FIRMS VIIRS satellite thermal observations with official incident dispatches from CAL FIRE, the US Forest Service (Region 5), and the California Governor's Office of Emergency Services (Cal OES), this interactive dashboard provides crucial situational awareness for communities from Redding and Santa Rosa to Los Angeles, Riverside, and San Diego.
When searching for a fire map california, california wildfire map, or checking where are the fires in california, understanding the state's dual fire seasons and diverse biomes is vital. California encompasses Mediterranean chaparral shrublands, dense mixed-conifer timber canopies in the Klamath and Sierra Nevada mountains, and arid desert interfaces. While Northern California timber fires typically peak in late summer under lightning outbreaks, Southern California's most catastrophic fire weather occurs in autumn and winter when fierce Santa Ana and Sundowner offshore winds align with critically parched fuel beds.
Active Complexes Across Northern & Southern California (SoCal)
CAL FIRE and federal wildland crews continuously battle multiple active incidents and emerging fire starts:
- Southern California (SoCal Fire Map & Incidents): Dense chaparral and scrub fuel beds across Los Angeles, Ventura, San Bernardino, and Riverside counties present extreme urban-wildland interface hazards. Incidents including the Buzzard Fire near Lebec, Ridge Fire in Gorman, Antelope Fire near Shandon, and Mateo Fire challenge initial attack crews when dry Santa Ana winds funnel through mountain passes.
- Northern California Timber Belts: Blazes in Shasta, Siskiyou, Trinity, and Butte counties burn through heavy conifer stands and dry slash, requiring heavy helitack support and bulldozer containment lines across steep volcanic canyons. Notable incidents include the 3-1 Pit Fire, Chileno Fire, and Rock Fire.
- Sierra Nevada Foothills & Central Zone: Ponderosa pine and oak woodlands affected by historic bark beetle mortality, where steep river drainages can funnel flame fronts toward foothill communities such as Auburn, Placerville, and Sonora.
Meteorological Catalysts: Santa Ana, Diablo & Sundowner Windstorms
California's most destructive wildfires are driven by offshore wind events. In Northern California, Diablo winds blow hot, dry continental air from the Great Basin across the Sierra crest, compressing and superheating as they plunge toward the San Francisco Bay Area. In Southern California, Santa Ana winds force dry air through Cajon, Soledad, and San Gorgonio passes at speeds exceeding 60 to 80 mph, dropping relative humidity below 5%. Under these critical Red Flag Warning regimes, flying embers can leap ahead of main flame fronts by one to two miles, igniting structure-to-structure conflagrations before ground engines can arrive.
Evacuation Preparedness & Home Hardening Protocols
California property owners in designated Very High Fire Hazard Severity Zones (VHFHSZ) are legally required to maintain 100 feet of defensible space around habitable structures under California Public Resources Code 4291:
- Zone 0 (Ember-Resistant Zone, 0 to 5 feet): Eliminate all combustible materials, mulch, and dried plants from the home perimeter. Replace wood fencing attached to structures with non-combustible gates.
- Zone 1 (Lean, Clean & Green, 5 to 30 feet): Space tree canopies at least 10 feet apart and prune lower branches 6 feet off the ground to eliminate ladder fuels.
- Zone 2 (Reduced Fuel Zone, 30 to 100 feet): Mow dry annual grasses down to a maximum height of 4 inches and clear fallen leaves and needles.
Sign up for emergency alerts through your county Office of Emergency Services (such as AlertLA, ReadySBC, or AlertSanDiego), pack your 72-hour survival kit with N95 smoke respirators, and adhere to all mandatory evacuation orders without delay.

Comprehensive multi-year telemetry, historical burn extent graphs, and environmental fuel analysis.
| Key Parameter | Regional Value / Characteristics | Operational Significance |
|---|---|---|
| Dominant Fuel Complex | Chamise chaparral, coastal sage scrub & Sierra mixed conifer | Determines crown fire transmission and rate of combustion |
| 10-Yr Mean Burn Area | 1,150,000 acres (465,400 ha) | Historical baseline for multi-year fire cycle variance |
| Ignition Source Ratio | 68% Human / Utility · 32% Dry Lightning | Drives prevention patrols vs. dry lightning tracking |
| Critical Fire Weather Driver | Santa Ana & Diablo offshore dry winds (gusts 55–80 mph) | Triggers Red Flag Warnings and extreme rate of spread |
| Flame Spread Velocity | Extreme: 160–340 chains/hr (2.0–4.2 mph) in wind-aligned brush | Dictates initial attack evacuation lead times |
| WUI Exposure Rating | Tier 1 Critical: 4.8 million residential structures in WUI zones | Determines structural defense assets and evacuation tiers |
Fire Ecology & Suppression Dynamics in California
California presents one of the most hazardous fire regimes on Earth due to the collision of Mediterranean bioclimates, combustible chaparral shrublands, and dense wildland-urban interface (WUI) development. Analysis of multi-year fire return intervals demonstrates significant volatility: wet winter atmospheric rivers stimulate explosive growth of herbaceous fine fuels (1-hour flash fuels), which cure rapidly under triple-digit summer heatwaves. When synoptic offshore pressure gradients develop in autumn—manifesting as the Diablo winds in the north and Santa Ana winds in the south—relative humidity plunges below 10%, generating catastrophic fire weather conditions where airborne ember showers travel over two miles ahead of active flame fronts.
Suppression operations managed by CAL FIRE and the U.S. Forest Service prioritize aggressive initial attack using multi-tier aviation assets, including McDonnell Douglas DC-10 and Boeing 747 Global SuperTankers dropping long-term phosphate retardant to establish containment anchors. In high-density WUI corridors such as the Sierra Nevada foothills and southern California mountain canyons, structure survival hinges strictly upon adherence to California Public Resources Code 4291, mandating 100 feet of defensible space and hardened Class-A non-combustible building materials to mitigate convective and radiant heat transfers.
