Wildfire Smoke & Air Quality Tracker: Live Conditions

For current wildfire activity, visit our Live U.S. Wildfire Tracker.

🔥 Wildfire Smoke & Air Quality Tracker

Track wildfire smoke, PM2.5 pollution, active fires and current air quality conditions across the United States using authoritative environmental and wildfire data sources.

Live data — map layers and AQI readings update according to each source network's publishing cycle.

Understanding the AQI Scale

The U.S. Air Quality Index (AQI) is EPA's 0–500 scale for communicating air-pollution conditions and associated health concerns. During wildfire smoke events, fine particulate matter (PM2.5) is often the primary pollutant of concern. Higher AQI values indicate greater potential health risk.

0–50
Good
Air quality is satisfactory and air pollution poses little or no risk.
51–100
Moderate
Air quality is acceptable, although unusually sensitive people may experience effects.
101–150
Unhealthy for Sensitive Groups
Sensitive groups may experience health effects while the general public is less likely to be affected.
151–200
Unhealthy
Some members of the public may experience health effects; sensitive groups may experience more serious effects.
201–300
Very Unhealthy
Health alert conditions. The risk of health effects is increased for everyone.
301+
Hazardous
Health warning of emergency conditions. Everyone is more likely to be affected.

🔥 Live U.S. Fire, Smoke & Air Quality Map

Explore current PM2.5 air quality, wildfire activity and smoke conditions using the AirNow Fire & Smoke Map. The map combines information from government air-quality monitors, temporary smoke monitors, participating air-sensor networks and federal fire and smoke datasets.

Source: AirNow Fire & Smoke Map — a collaborative product of the U.S. Environmental Protection Agency (EPA) and U.S. Forest Service. Map information includes PM2.5 air quality, wildfire and smoke information from participating monitoring and federal data networks.

💡 Map tip: Open the map's layer controls to explore permanent and temporary air-quality monitors, air sensors, NOAA smoke plumes, Smoke Outlooks, fire incidents, fire perimeters and satellite fire detections. PurpleAir sensor information is available through the map's air-sensor layers.

What to Do at Each AQI Level

General guidance based on U.S. AQI categories. Individual health needs vary, so follow advice from healthcare providers and local public-health officials when smoke or poor air quality affects your area.

AQI Level General Guidance
Good / Moderate Most people can continue normal outdoor activities. Unusually sensitive individuals should pay attention to symptoms as pollution levels increase.
Unhealthy for Sensitive Groups People in sensitive groups should consider reducing prolonged or heavy outdoor exertion and follow local health guidance.
Unhealthy Consider reducing prolonged or heavy outdoor activity. Sensitive groups should take additional precautions and follow official health recommendations.
Very Unhealthy Reduce outdoor activity and exposure. Follow recommendations from local health departments and air-quality authorities.
Hazardous Avoid unnecessary exposure and follow emergency and public-health guidance issued for your area.

About This Tracker

What the map shows: The AirNow Fire & Smoke Map brings together current particle-pollution information with wildfire locations, smoke information and Smoke Outlooks where available.

Air sensors: The map can include measurements from permanent monitoring stations, temporary monitors and participating lower-cost sensor networks. Sensor information is intended to supplement, not replace, regulatory monitoring.

Smoke plumes: Satellite-detected smoke plumes indicate smoke visible in the atmosphere. A plume shown overhead does not necessarily mean smoke is affecting ground-level air quality at that location.

Fire detections: Satellite fire detections and mapped fire locations should be used as situational information rather than as the sole basis for evacuation or emergency decisions.

Updates: Data can be delayed or temporarily unavailable because the individual monitoring, satellite and reporting systems update on different schedules.

Sources & methodology: The primary interactive map is the AirNow Fire & Smoke Map , developed collaboratively by the U.S. Environmental Protection Agency and U.S. Forest Service. The map incorporates information from multiple monitoring, sensor, fire and smoke datasets. Additional wildfire resources on this page include NASA FIRMS, InciWeb and the National Interagency Fire Center.

Important: Orbis Weather does not issue official air-quality alerts, wildfire evacuation orders or public-health warnings. Always follow instructions from local authorities, emergency management, public-health agencies and official government weather and air-quality services.
