Kongola fire, 2 September 2025 Kongola

Out · last detection 25 Sept 2025, 23:40 UTC

The fire started on 2 September 2025 in Kongola, Namibia, and satellites saw it burning for 24 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 28,662 hectares from heat detections, spread across a single municipality.

Number 5 in Namibia in 2025, of 87.

GWIS near-real-time perimeter, from the layer that changed in August 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

81% of the perimeter overlaps earlier fires recorded since 2016: 6,926 ha in 2016, 4,858 ha in 2017, 9,415 ha in 2018, 790 ha in 2019, 7,240 ha in 2020, 163 ha in 2021, 5,750 ha in 2022, 6,138 ha in 2023, 4,685 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 23,188 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.

Inside 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 Kongola fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 2 September 2025 to 25 September 2025 (24 days). The perimeter dates it from 2 September 2025 to 21 September 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 28,662 hectares (286.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kongola (14,861 ha, 2.9 %).
What was the weather like?
During the fire the temperature reached 37.4 °C, humidity dropped to 8 % and gusts hit 48 km/h. The fire danger index (FWI) reached 67, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Namibia (OCHA COD-AB). 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; 2 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 2 September 2025 to 21 September 2025. 843 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.

How we build fire pages: methodology

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 OCHA COD-AB (Namibia Statistics Agency (NSA)) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-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.
