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.
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.
🔥 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.
Current AQI — Fire-Prone Metro Areas
Current AirNow AQI information for selected U.S. metro areas frequently affected by wildfire smoke. These widgets provide a quick city-level view alongside the more detailed national Fire & Smoke Map above.

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.
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.
