Saurimo fire, 11 August 2026 Saurimo
The fire started on 11 August 2026 in Saurimo, Angola, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 10,114 hectares from heat detections, spread across a single municipality.
It is the 48th largest in Lunda Sul since 2016 (of 240 with a page). Number 162 in Angola in 2026, of 486.

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 more than two months without rain (1 mm or more) when it started.
This area had burned before
99% of the perimeter overlaps earlier fires recorded since 2016: 4,255 ha in 2016, 2,976 ha in 2017, 3,353 ha in 2018, 5,776 ha in 2019, 3,690 ha in 2020, 3,428 ha in 2021, 4,835 ha in 2022, 5,049 ha in 2023, 3,365 ha in 2024, 3,048 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 10,013 ha that had burned before.

What happened to each town
-
Saurimo where it started10,160 ha reached on 11 Aug0.4 %
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.

The smoke
CAMS · CopernicusOn 19 August 2026 the air beside the fire reached 104 µg/m³ of PM2.5. That day averaged 77: 5.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Saurimo fire last?
- GWIS (Copernicus) dates it between 11 August 2026 and 22 August 2026: 12 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 10,114 hectares (101.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Saurimo (10,160 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 33.0 °C, humidity dropped to 14 % and gusts hit 39 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.
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 (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.
