Madibeng fire, 18 July 2026 Madibeng

Out · last detection 24 Jul 2026, 11:34 UTC

The fire started on 18 July 2026 in Madibeng, South Africa, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,851 hectares from heat detections, spread across a single municipality.

It is the 45th largest in North West since 2016 (of 171 with a page). Number 47 in South Africa in 2026, of 149.

The power measured by the satellite is low (16.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 26 days without rain (1 mm or more) when it started.

This area had burned before

85% of the perimeter overlaps earlier fires recorded since 2016: 970 ha in 2017, 313 ha in 2019, 23 ha in 2020, 1,556 ha in 2021, 1,886 ha in 2022, 510 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 3,290 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 2.4% of the area of London (39 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 area1.9 ha
Residents≈ 50

Inside the perimeter there were about 1.9 hectares of built-up land and about 50 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 Madibeng fire last?
GWIS (Copernicus) dates it between 18 July 2026 and 24 July 2026: 7 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 3,851 hectares (38.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Madibeng (3,857 ha, 1.0 %).
What was the weather like?
During the fire the temperature reached 27.7 °C, humidity dropped to 8 % and gusts hit 30 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 South Africa (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 from the perimeter: the VIIRS detections inside it did not change them. 158 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 geoBoundaries ADM3 (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.
