Are there wildfires in Brazil right now?

NASA's FIRMS satellites detected 8236 active fire hotspots in Brazil over the last 3 days, including 59 high-intensity fires. The map on this page shows their exact locations, updated hourly.

How does NASA detect wildfires?

NASA's VIIRS and MODIS instruments aboard the Suomi NPP, NOAA-20 and Terra/Aqua satellites detect thermal anomalies (heat signatures) from orbit. Each detection is a "hotspot" — a pixel where the sensor measured fire-level heat. Data is published within about 3 hours of the satellite overpass through the FIRMS system.

What does fire intensity (FRP) mean?

FRP (Fire Radiative Power, in megawatts) measures how much energy a fire is releasing. Higher FRP means a more intense fire. On this map, brighter red dots are higher-intensity detections.

10 km/h from the ENE — carrying smoke towards the WSW.

34°C · 51% humidity

Air quality Extremely poor

PM2.5 107.8 µg/m³ this hour · EU AQI 194 · US AQI 189

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.
