Bandafassi fire, 12 January 2023 Bandafassi
The fire started on 12 January 2023 in Bandafassi, Senegal, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 9,887 hectares from heat detections, spread across a single municipality.
It is the 12th largest in Kédougou since 2016 (of 116 with a page). Number 4 in Senegal in 2023, of 83.

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
79% of the perimeter overlaps earlier fires recorded since 2016: 4,807 ha in 2016, 1,883 ha in 2017, 479 ha in 2018, 15 ha in 2019, 4,368 ha in 2020, 1,833 ha in 2021, 1,319 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 7,826 ha that had burned before.

What happened to each town

Bandafassi where it started9,959 ha reached on 13 Jan1.7 %
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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 0.11 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions
- How long did the Bandafassi fire last?
- GWIS (Copernicus) dates it between 12 January 2023 and 15 January 2023: 4 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 9,887 hectares (98.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Bandafassi (9,959 ha, 1.7 %).
- What was the weather like?
- During the fire the temperature reached 38.2 °C, humidity dropped to 12 % and gusts hit 39 km/h. The fire danger index (FWI) reached 55, 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 from the perimeter: the VIIRS detections inside it did not change them. 333 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
