As of now, multiple wildfires are actively burning across California, driven by seasonal winds, dry vegetation, and extreme weather. This live guide shows how to locate an up‑to‑date map of fires in California, explains how to interpret fire size, containment, and perimeters, and lists official agencies and tools you can rely on. In the opening overview below, you will find an answer‑first snapshot of current activity, followed by evergreen explanations of fire terminology, map layers, and evacuation best practices that stay useful across seasons.
Where to Find the Authoritative Real‑Time Map
For the most reliable, continuously updated view, use the California Department of Forestry and Fire Protection (CAL FIRE) incident map, which displays active fires, historical incidents, and perimeters. Complementary data come from the National Interagency Fire Center (NIFC), the U.S. Forest Service, and local fire departments, all of which pull from fire‑behavior models and infrared overflights. Satellite layers from NOAA and commercial providers can show smoke plumes and heat signatures, but they may include older detections or false positives, so always cross reference with official incident pages.
How to Read a Live Fire Map
Understand the symbols and overlays so you can interpret risk and progression at a glance:
- Perimeter (solid line): The confirmed boundary of the fire.
- Containment percentage: The proportion of the perimeter that fire lines have secured.
- Active flare‑ups (shading or icons): Areas where fire is still spreading within the perimeter.
- Smoke plume (transparent overlay): Shows prevailing wind direction and potential exposure paths.
- Evacuation zones and road closures: Often added as separate layers; treat these as high‑priority updates.
Current Activity Snapshot (Illustrative)
Below is an evergreen table pattern you can revisit for status checks. Specific incidents change frequently; treat this as a template for how verified attributes are recorded rather than a snapshot of today’s exact list.
| Fire Name / Area | Size (acres) | Containment | Primary Threats | Last Verified | Official Source |
|---|---|---|---|---|---|
| Example Fire — North County | 3,200 | 35% | Structures, I‑5 corridor | Timestamp | CAL FIRE / Incident Page |
| Example Fire — Sierra Foothills | 8,700 | 12% | Rural communities, air quality | Timestamp | USFS / NIFC |
| Example Fire — Desert Region | 1,100 | 60% | Minimal structures, HR&W concerns | Timestamp | CAL FIRE / NIFC |
Fire Size, Behavior, and Common Terms
Fire Size and Rate of Spread
Fire size is reported in acres in the United States; 1 acre is about 0.4 hectares. A fire that doubles from 100 to 200 acres in six hours is spreading faster than one that grows from 1,000 to 1,200 acres in the same period. Rate of spread matters more than absolute size when evaluating immediate danger.
Containment vs. Control
Containment refers to the proportion of the fire perimeter that has a control line, such as dozer lines, hand lines, or natural barriers. A fire can be 50% contained yet still produce active spot fires ahead of the perimeter. Full control means the fire is expected to no longer grow, while full containment means the boundary is secured and mop‑up can continue.
Spotting and Crown Fire
Spotting occurs when embers jump ahead of the main fire, igniting spot fires. Crown fire moves through the canopy and is harder to suppress; maps rarely show real‑time spotting location, so treat any uncontained fire as capable of sudden jumps under extreme weather.

How to Use Map Layers for Specific Needs
Toggle layers to focus on what matters to you:
- Evacuation zones if you need to know mandatory or voluntary orders.
- Road closures for travel planning and emergency routes.
- Wind overlays to anticipate where smoke and embers may travel.
- Infrastructure layers (power, water) if you are assessing community risk.
Keep in mind that some layers are predictive (e.g., smoke dispersion models) and should be used alongside observed fire perimeter data.
Health and Safety Guidance During Active Fires
If you are near an active fire, prioritize evacuation orders and local alerts. If you must remain indoors, close windows, use air purifiers if available, and avoid vigorous outdoor activity when smoke is heavy. Sensitive groups — children, older adults, and people with respiratory conditions — should reduce exposure aggressively. Stay informed via official channels rather than relying solely on social media screenshots, which can be outdated or mislabeled.
Preparing an Evergreen Fire Action Checklist
Use this simple checklist to stay ready across fire seasons:
- Bookmark CAL FIRE and local agency map URLs.
- Know multiple evacuation routes from your home and workplace.
- Keep an emergency kit with documents, medications, water, and N95 masks.
- Confirm whether your phone has Wireless Emergency Alerts (WEA) enabled.
- Practice shutting off utilities and designating an out‑of‑area contact.
Frequently Asked Questions (Evergreen)
How often do maps update during an active fire?
Incident maps typically refresh every 15–60 minutes when a fire is active, perimeters may be updated after each mapping flight or ground survey. Evacuation orders can change with shorter notice, so enable alerts.
What does a red perimeter versus a yellow perimeter mean?
Red usually indicates the active fire edge with recent spotting or forward movement; yellow often marks the perimeter where fire behavior has moderated or where control lines are holding. Always read the map legend for the specific incident.
Can satellite smoke layers show where I will experience unhealthy air?
Satellite smoke products provide a regional overview and are useful for trends, but they do not replace local air quality measurements. Check AQI monitors near you for health decisions.
Are older fire perimeters removed from maps once the fire is contained?
For transparency, many agencies keep historical perimeters visible for a period, often layered under newer incidents, so you can see how a fire grew over time.
