It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 29 Oct.

This area had burned before

87% of the perimeter overlaps earlier fires recorded since 2016: 6,742 ha in 2016, 1,977 ha in 2017, 2,133 ha in 2018, 938 ha in 2019, 3,534 ha in 2020, 2,319 ha in 2021, 1,913 ha in 2022, 1,355 ha in 2023, 1,146 ha in 2024, 3,402 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 12,392 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 9% of the area of London (142 km² against 1,583 km²).

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.

Built-up area< 0.1 ha
Residents< 20

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 Sanga fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 4 October 2026 to 20 October 2026 (17 days). The perimeter dates it from 6 October 2026 to 13 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 14,231 hectares (142.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Sanga (14,302 ha, 1.1 %).
Is the Sanga fire still active?
No fire detections since 20 Oct 2026, 11:51 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 36.5 °C, humidity dropped to 24 % and gusts hit 42 km/h. The fire danger index (FWI) reached 38, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mozambique (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 6 October 2026 to 13 October 2026. 305 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
  • 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.

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 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
