Koulor fire, 23 October 2026 Koulor

Out · last detection 1 Nov 2026, 14:56 UTC

The fire started on 23 October 2026 in Koulor, Senegal, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,063 hectares from heat detections, spread across a single municipality.

It is the 280th largest in Tambacounda since 2016 (of 297 with a page). Number 128 in Senegal in 2026, of 132.

It had gone 12 days without rain (1 mm or more) when it started.

This area had burned before

63% of the perimeter overlaps earlier fires recorded since 2016: 459 ha in 2018, 355 ha in 2021, 266 ha in 2022, 1,042 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,293 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.3% of the area of London (21 km² against 1,583 km²).

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area 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.

Frequently asked questions

How long did the Koulor fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 23 October 2026 to 1 November 2026 (10 days). The perimeter dates it from 23 October 2026 to 30 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,063 hectares (20.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Koulor (2,072 ha, 0.3 %).
Is the Koulor fire still active?
No fire detections since 1 Nov 2026, 14:56 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 38.1 °C, humidity dropped to 27 % and gusts hit 39 km/h. The fire danger index (FWI) reached 24, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Senegal (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.

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 18.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 23 October 2026 to 30 October 2026. 22 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.

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 3.0 Intergovernmental Organisations (CC BY 3.0 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.
