It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 4.0 mm on 25 Sept.

This area had burned before

93% of the perimeter overlaps earlier fires recorded since 2016: 287 ha in 2017, 729 ha in 2018, 486 ha in 2019, 882 ha in 2020, 1,054 ha in 2022, 3,205 ha in 2023, 2,417 ha in 2024, 5,661 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 5,726 ha that had burned before.

How big is it?

Frequently asked questions

How long did the Massango fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 8 September 2026 to 24 September 2026 (17 days). The perimeter dates it from 13 September 2026 to 20 September 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,132 hectares (61.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Massango (6,175 ha, 0.8 %).
What was the weather like?
During the fire the temperature reached 32.8 °C, humidity dropped to 36 % and gusts hit 35 km/h. The fire danger index (FWI) reached 18, class Moderate.
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.

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 13 September 2026 to 20 September 2026. 106 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.
