Mossuril fire, 20 October 2025 Mossuril
The fire started on 20 October 2025 in Mossuril, Mozambique, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,723 hectares from heat detections, spread across a single municipality.
It is the 244th largest in Nampula since 2016 (of 392 with a page). Number 212 in Mozambique in 2025, of 313.

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 12 days without rain (1 mm or more) when it started. Rain came after the fire: 2.3 mm on 11 Nov.
This area had burned before
80% of the perimeter overlaps earlier fires recorded since 2016: 1,915 ha in 2016, 349 ha in 2018, 502 ha in 2019, 1,197 ha in 2020, 1,150 ha in 2021, 1,572 ha in 2022, 1,940 ha in 2023, 560 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 2,997 ha that had burned before.

What happened to each town

Mossuril where it started3,749 ha reached on 20 Oct1.1 %
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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 1.8 hectares of built-up land and about 250 residents (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.

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 4 November 2025 the air beside the fire reached 23 µg/m³ of PM2.5. That day averaged 17: 1.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Mossuril fire last?
- GWIS (Copernicus) dates it between 20 October 2025 and 3 November 2025: 15 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 3,723 hectares (37.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mossuril (3,749 ha, 1.1 %).
- What was the weather like?
- During the fire the temperature reached 33.0 °C, humidity dropped to 46 % and gusts hit 56 km/h. The fire danger index (FWI) reached 29, class 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 from the perimeter: the VIIRS detections inside it did not change them. 124 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.
- 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.
