Namarrói fire, October 2025 Namarrói
Out · last detection 4 Nov 2025, 11:41 UTC
The fire started on 9 October 2025 in Namarrói, Mozambique, and satellites saw it burning for 27 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,434 hectares from heat detections, spread across a single municipality.
Number 115 in Mozambique in 2025, of 312.
GWIS near-real-time perimeter, from the layer that changed in August 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

People and buildings inside the perimeter

Residents≈ 1,100
Inside the perimeter there were about 12 hectares of built-up land and about 1,100 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.

Frequently asked questions
- How long did the Namarrói fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 9 October 2025 to 4 November 2025 (27 days). The perimeter dates it from 16 October 2025 to 2 November 2025.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,434 hectares (54.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Namarrói (5,467 ha, 1.8 %).
- What was the weather like?
- During the fire the temperature reached 37.1 °C, humidity dropped to 18 % and gusts hit 46 km/h. The fire danger index (FWI) reached 41, 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.
Report an error
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 16 October 2025 to 2 November 2025. 173 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.
