Komboya fire, April 2024 Komboya, Wandor
The fire started on 14 April 2024 in Komboya, Sierra Leone, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,103 hectares from heat detections, spread across 2 municipalities.
It is the 303th largest in Southern since 2016 (of 393 with a page). Number 102 in Sierra Leone in 2024, of 141.

This area had burned before
99% of the perimeter overlaps earlier fires recorded since 2016: 538 ha in 2016, 5 ha in 2017, 33 ha in 2021, 943 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 1,095 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 were about 0.18 hectares of built-up land and about 150 residents (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.

The smoke
CAMS · CopernicusOn 17 April 2024 the air beside the fire reached 92 µg/m³ of PM2.5. That day averaged 65: 4.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Komboya fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 14 April 2024 to 16 April 2024 (3 days). The perimeter dates it from 15 April 2024 to 15 April 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,103 hectares (11.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Komboya (916 ha, 3.7 %); Wandor (194 ha, 0.6 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Sierra Leone (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 15 April 2024 to 15 April 2024. 26 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- 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 4.0 (CC BY 4.0)). 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.
