Koussané fire, January 2026 Koussané
The fire started on 11 January 2026 in Koussané, Mali, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,802 hectares from heat detections, spread across a single municipality.
It is the 32th largest in Kayes since 2016 (of 333 with a page). Number 13 in Mali in 2026, of 116.
The power measured by the satellite is low (24.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 2 days without rain (1 mm or more) when it started.
This area had burned before
26% of the perimeter overlaps earlier fires recorded since 2016: 1,329 ha in 2024, 204 ha in 2025.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 9 January 2026 the air beside the fire reached 229 µg/m³ of PM2.5. That day averaged 178: 12 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Koussané fire last?
- GWIS (Copernicus) dates it between 11 January 2026 and 14 January 2026: 4 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,802 hectares (58.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Koussané (5,845 ha, 1.8 %).
- What was the weather like?
- During the fire the temperature reached 35.5 °C, humidity dropped to 16 % and gusts hit 40 km/h. The fire danger index (FWI) reached 46, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mali (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.
Satellite cross-check
Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM3 (Creative Commons Attribution 4.0 International (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
