Zumbu fire, 16 October 2026 Zumbu

Out · last detection 25 Oct 2026, 11:57 UTC

The fire started on 16 October 2026 in Zumbu, Mozambique, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,590 hectares from heat detections, spread across a single municipality.

It is the 16th largest in Tete since 2016 (of 116 with a page). Number 129 in Mozambique in 2026, of 552.

The power measured by the satellite is low (22.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 10 days without rain (1 mm or more) when it started.

This area had burned before

46% of the perimeter overlaps earlier fires recorded since 2016: 682 ha in 2016, 844 ha in 2017, 2,450 ha in 2019, 2,065 ha in 2021, 1,732 ha in 2022, 2,248 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,525 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 4.8% of the area of London (76 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 Zumbu fire last?
GWIS (Copernicus) dates it between 16 October 2026 and 25 October 2026: 10 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 7,590 hectares (75.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Zumbu (7,644 ha, 0.6 %).
Is the Zumbu fire still active?
No fire detections since 25 Oct 2026, 11:57 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 42.2 °C, humidity dropped to 12 % and gusts hit 63 km/h. The fire danger index (FWI) reached 67, class Extreme.
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 from the perimeter: the VIIRS detections inside it did not change them. 186 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.

How we build fire pages: methodology ›

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.
