Out · last detection 7 Sept 2026, 12:36 UTC

The fire started on 27 July 2026 in Muconda, Angola, and satellites saw it burning for 43 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 47,992 hectares from heat detections, spread across 2 municipalities.

It is the 2th largest in Lunda Sul since 2016 (of 240 with a page). Number 21 in Angola in 2026, of 487.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 13 Sept.

This area had burned before

96% of the perimeter overlaps earlier fires recorded since 2016: 14,948 ha in 2016, 20,543 ha in 2017, 10,985 ha in 2018, 14,484 ha in 2019, 23,275 ha in 2020, 13,188 ha in 2021, 11,663 ha in 2022, 16,517 ha in 2023, 11,160 ha in 2024, 16,243 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 45,855 ha that had burned before.

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 Muconda fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 27 July 2026 to 7 September 2026 (43 days). The perimeter dates it from 29 July 2026 to 31 August 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 47,992 hectares (479.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Muconda (36,612 ha, 1.3 %); Saurimo (11,697 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 34.1 °C, humidity dropped to 13 % and gusts hit 42 km/h. The fire danger index (FWI) reached 46, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Angola (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; 3 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 29 July 2026 to 31 August 2026. 1,294 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 ADM2 (Public Domain). 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.
