Lubefu fire, 26 July 2025 Lubefu
The fire started on 26 July 2025 in Lubefu, Congo - Kinshasa, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,270 hectares from heat detections, spread across a single municipality.
It is the 113th largest in Sankuru since 2016 (of 187 with a page). Number 56 in Congo - Kinshasa in 2025, of 118.

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 9 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 9 Aug.
This area had burned before
93% of the perimeter overlaps earlier fires recorded since 2016: 2,878 ha in 2016, 963 ha in 2017, 5,502 ha in 2018, 5,179 ha in 2020, 3,974 ha in 2021, 3,293 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 6,737 ha that had burned before.
What happened to each town

Lubefu where it started7,325 ha reached on 26 Jul0.5 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre 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.

The smoke
CAMS · CopernicusOn 1 August 2025 the air beside the fire reached 89 µg/m³ of PM2.5. That day averaged 62: 4.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Lubefu fire last?
- GWIS (Copernicus) dates it between 26 July 2025 and 5 August 2025: 11 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 7,270 hectares (72.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Lubefu (7,325 ha, 0.5 %).
- What was the weather like?
- During the fire the temperature reached 33.5 °C, humidity dropped to 19 % and gusts hit 44 km/h. The fire danger index (FWI) reached 44, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Congo - Kinshasa (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.
Satellite cross-check
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.

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 ADM2 (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.
