Oshwe fire, August 2020 Oshwe, Idiofa
The fire started on 2 August 2020 in Oshwe, Congo - Kinshasa, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 9,667 hectares from heat detections, spread across 2 municipalities.
It is the largest fire in Mai-Ndombe since 2016 (of 10 with a page). Number 43 in Congo - Kinshasa in 2020, of 165.

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 7 days without rain (1 mm or more) when it started. Rain came after the fire: 5.1 mm on 21 Aug.
This area had burned before
77% of the perimeter overlaps earlier fires recorded since 2016: 4,751 ha in 2017, 2,063 ha in 2018, 5,571 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 7,487 ha that had burned before.

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.

Frequently asked questions
- How long did the Oshwe fire last?
- GWIS (Copernicus) dates it between 2 August 2020 and 18 August 2020: 17 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 9,667 hectares (96.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Oshwe (9,443 ha, 0.2 %); Idiofa (295 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 34.2 °C, humidity dropped to 37 % and gusts hit 33 km/h. The fire danger index (FWI) reached 25, class 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.
