Cuilo fire, 7 July 2026 Cuilo
The fire started on 7 July 2026 in Cuilo, Angola, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 10,134 hectares from heat detections, spread across a single municipality.
It is the 88th largest in Lunda Norte since 2016 (of 411 with a page). Number 161 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 54 days without rain (1 mm or more) when it started.
This area had burned before
49% of the perimeter overlaps earlier fires recorded since 2016: 654 ha in 2017, 1,091 ha in 2018, 711 ha in 2019, 1,057 ha in 2020, 2,248 ha in 2021, 933 ha in 2022, 296 ha in 2023, 291 ha in 2024, 835 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 4,939 ha that had burned before.
What happened to each town

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 9 July 2026 the air beside the fire reached 96 µg/m³ of PM2.5. That day averaged 62: 4.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Cuilo fire last?
- GWIS (Copernicus) dates it between 7 July 2026 and 9 July 2026: 3 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 10,134 hectares (101.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Cuilo (10,191 ha, 1.0 %).
- What was the weather like?
- During the fire the temperature reached 31.1 °C, humidity dropped to 21 % and gusts hit 40 km/h. The fire danger index (FWI) reached 42, 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.
