Ouèssè fire, 23 January 2026 Ouèssè
The fire started on 23 January 2026 in Ouèssè, Benin, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,431 hectares from heat detections, spread across a single municipality.
It is the 20th largest in Collines since 2016 (of 47 with a page). Number 58 in Benin in 2026, of 99.
The power measured by the satellite is low (13.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 smoke
CAMS · CopernicusOn 28 January 2026 the air beside the fire reached 99 µg/m³ of PM2.5. That day averaged 77: 5.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Ouèssè fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 23 January 2026 to 30 January 2026 (8 days). The perimeter dates it from 24 January 2026 to 30 January 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,431 hectares (14.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Ouèssè (1,441 ha, 0.5 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Benin (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 ADM2 (Public Domain). 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.
