Macossa fire, 30 August 2025 Macossa

Out · last detection 23 Sept 2025, 11:27 UTC

The fire started on 30 August 2025 in Macossa, Mozambique, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,430 hectares from heat detections, spread across a single municipality.

It is the 28th largest in Manica since 2016 (of 198 with a page). Number 61 in Mozambique in 2025, of 313.

It had gone 32 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 27 Sept.

This area had burned before

96% of the perimeter overlaps earlier fires recorded since 2016: 3,466 ha in 2016, 2,964 ha in 2017, 1,444 ha in 2018, 1,513 ha in 2019, 1,571 ha in 2020, 1,747 ha in 2021, 1,347 ha in 2022, 1,606 ha in 2023, 2,556 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 8,118 ha that had burned before.

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.

Frequently asked questions

How long did the Macossa fire last?
GWIS (Copernicus) dates it between 30 August 2025 and 23 September 2025: 25 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 8,430 hectares (84.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Macossa (8,461 ha, 0.9 %).
What was the weather like?
During the fire the temperature reached 35.7 °C, humidity dropped to 16 % and gusts hit 48 km/h. The fire danger index (FWI) reached 50, 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.

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 (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.
