Ouindigui fire, 21 October 2026 Ouindigui, Rollo
The fire started on 21 October 2026 in Ouindigui, Burkina Faso, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,326 hectares from heat detections, spread across 2 municipalities.
It is the 47th largest in Yaadga since 2016 (of 74 with a page). Number 115 in Burkina Faso in 2026, of 191.
The power measured by the satellite is low (12.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.
Compare with…
Is it still active?
No detections since 23 Oct 2026, 13:40 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

The weather it burned in
It had gone 10 days without rain (1 mm or more) when it started.
This area had burned before
45% of the perimeter overlaps earlier fires recorded since 2016: 591 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 23 October 2026 the air beside the fire reached 51 µg/m³ of PM2.5. That day averaged 41: 2.7 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Ouindigui fire last?
- GWIS (Copernicus) dates it between 21 October 2026 and 23 October 2026: 3 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 1,326 hectares (13.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Ouindigui (849 ha, 1.3 %); Rollo (485 ha, 0.8 %).
- Is the Ouindigui fire still active?
- No fire detections since 23 Oct 2026, 13:40 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 39.0 °C, humidity dropped to 14 % and gusts hit 31 km/h. The fire danger index (FWI) reached 39, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Burkina Faso (OCHA COD-AB). 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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 17 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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 OCHA COD-AB (Institut Geographique Burkina (IGB)) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-IGO)). 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.
