How long did the Koulor fire last?

According to the heat detections seen by satellite, it burned from 14 October 2026 to 22 October 2026 (9 days between the first and the last detection). There is no perimeter yet to date it.

How much area did it burn?

There is no perimeter yet. Heat detections rebuild about 2,366 hectares with fire (23.7 km²), a rough figure; GWIS will give its own when it publishes the perimeter, which can take several days.

Which municipalities burned?

The fire only entered Koulor (2,366 ha, 0.4 %).

Is the Koulor fire still active?

No fire detections since 23 Oct 2026, 15:01 UTC. A lack of detections is not an official extinction.

What was the weather like?

During the fire the temperature reached 36.3 °C, humidity dropped to 30 % and gusts hit 32 km/h. The fire danger index (FWI) reached 16, class Moderate.

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.

GWIS (Copernicus) has not yet published the perimeter of this fire. It rebuilds it from hotspots, which can take several days, and it does not always arrive. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). If the perimeter arrives, this page picks it up on its own and keeps the same address.

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.

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.

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

No perimeter yet: the area (≈ 2,366 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
Dates of the first and last VIIRS detection of the cluster. 199 Suomi-NPP VIIRS detections on those dates.
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 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.
