Mpungu fire, 20 September 2025 Mpungu

Out · last detection 28 Sept 2025, 00:43 UTC

The fire started on 20 September 2025 in Mpungu, Namibia, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,522 hectares from heat detections, spread across a single municipality.

It is the 119th largest in Kavango West since 2016 (of 152 with a page). Number 63 in Namibia in 2025, of 87.

No earlier perimeters overlap this fire since 2016, when the satellite record begins.

How big is it?

10 km
It burned the equivalent of 1.6% of the area of London (25 km² against 1,583 km²).

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 2025
Built-up area0.21 ha
Residents≈ 30

Inside the perimeter there were about 0.21 hectares of built-up land and about 30 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.

Frequently asked questions

How long did the Mpungu fire last?
GWIS (Copernicus) dates it between 20 September 2025 and 28 September 2025: 9 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 2,522 hectares (25.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mpungu (2,534 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 37.1 °C, humidity dropped to 6 % and gusts hit 55 km/h. The fire danger index (FWI) reached 78, class Very 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.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 56 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.
