Bandafassi fire, 31 January 2020 Bandafassi
The fire started on 31 January 2020 in Bandafassi, Senegal, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 14,503 hectares from heat detections, spread across a single municipality.
It is the 7th largest in Kédougou since 2016 (of 116 with a page). The largest in Senegal in 2020, of 72.

Where it burned
How it evolved, day by day
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 more than two months without rain (1 mm or more) when it started.
This area had burned before
34% of the perimeter overlaps earlier fires recorded since 2016: 1,390 ha in 2016, 1,728 ha in 2017, 2,889 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 4,869 ha that had burned before.

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 Bandafassi fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 31 January 2020 to 9 February 2020 (10 days). The perimeter dates it from 3 February 2020 to 9 February 2020.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 14,503 hectares (145.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Bandafassi (14,604 ha, 2.5 %).
- What was the weather like?
- During the fire the temperature reached 39.1 °C, humidity dropped to 7 % and gusts hit 45 km/h. The fire danger index (FWI) reached 67, class Extreme.
- 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.

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 3 February 2020 to 9 February 2020. 534 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 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.
