Wildfires in United States Today
Live active-fire map for the United States from NASA FIRMS satellite data. Where fires are burning right now — updated hourly. Typical fire season: summer–fall.
10 km/h from the SSE — carrying smoke towards the NNW.
25°C · 22% humidity
Air quality Extremely poor
PM2.5 136.4 µg/m³ this hour · EU AQI 300 · US AQI 399
Avoid outdoor exertion. Stay indoors with windows closed where possible.
The band above follows the European index, which averages particulates over 24 hours — so a sharp rise in this hour's PM2.5, as smoke passing overhead causes, shows up in the reading before it moves the band.
Wind direction only — not a smoke dispersion forecast. Air quality is modelled, not a street-level measurement. Weather from MET Norway; air quality from Open-Meteo (Copernicus CAMS). Both CC BY 4.0.

About this wildfire map
This map uses NASA's Fire Information for Resource Management System (FIRMS), which publishes active-fire detections from the VIIRS and MODIS instruments aboard NASA and NOAA satellites. Each dot is a thermal “hotspot” where the sensor measured fire-level heat, usually within 3 hours of the satellite passing overhead. It shows where fires are actively burning — not fire perimeters or evacuation zones. For safety and evacuation information, always follow your local emergency services.
