Cuito fire, May 2026 Cuito, Chinguar
The fire started on 28 May 2026 in Cuito, Angola, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,548 hectares from heat detections, spread across 2 municipalities.
It is the 24th largest in Bié since 2016 (of 64 with a page). Number 198 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 22 days without rain (1 mm or more) when it started.
This area had burned before
75% of the perimeter overlaps earlier fires recorded since 2016: 1,700 ha in 2016, 863 ha in 2017, 2,137 ha in 2018, 1,486 ha in 2019, 1,799 ha in 2020, 1,585 ha in 2021, 1,043 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 6,451 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.
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 17 June 2026 the air beside the fire reached 41 µg/m³ of PM2.5. That day averaged 27: 1.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Cuito fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 May 2026 to 26 June 2026 (30 days). The perimeter dates it from 4 June 2026 to 19 June 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 8,548 hectares (85.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Cuito (5,730 ha, 1.2 %); Chinguar (2,867 ha, 1.0 %).
- What was the weather like?
- During the fire the temperature reached 26.5 °C, humidity dropped to 21 % and gusts hit 49 km/h. The fire danger index (FWI) reached 41, 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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 4 June 2026 to 19 June 2026. 288 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.
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.
