Bilimono fire, 19 December 2023 Bilimono
The fire started on 19 December 2023 in Bilimono, Côte d’Ivoire, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,483 hectares from heat detections, spread across a single municipality.
It is the 51th largest in Savanes since 2016 (of 276 with a page). Number 16 in Côte d’Ivoire in 2023, of 117.
The power measured by the satellite is low (13.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

This area had burned before
100% of the perimeter overlaps earlier fires recorded since 2016: 2,113 ha in 2016, 1,646 ha in 2017, 1,158 ha in 2018, 1,362 ha in 2019, 1,341 ha in 2020, 1,720 ha in 2021, 813 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 2,493 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there was no noticeable 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 Bilimono fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 19 December 2023 to 26 December 2023 (8 days). The perimeter dates it from 19 December 2023 to 23 December 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,483 hectares (24.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Bilimono (2,500 ha, 0.7 %).
- What was the weather like?
- During the fire the temperature reached 35.4 °C, humidity dropped to 19 % and gusts hit 31 km/h. The fire danger index (FWI) reached 33, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Côte d’Ivoire (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 19 December 2023 to 23 December 2023. 62 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.
