Mossuril fire, October 2022 Mossuril
The fire started on 27 October 2022 in Mossuril, Mozambique, and satellites saw it burning for 16 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,689 hectares from heat detections, spread across a single municipality.
It is the 246th largest in Nampula since 2016 (of 392 with a page). Number 143 in Mozambique in 2022, of 206.

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 7 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 15 Nov.
This area had burned before
83% of the perimeter overlaps earlier fires recorded since 2016: 2,194 ha in 2016, 1,170 ha in 2019, 2,010 ha in 2020, 1,523 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 3,065 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.
The weather day by day
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.

Frequently asked questions
- How long did the Mossuril fire last?
- GWIS (Copernicus) dates it between 27 October 2022 and 11 November 2022: 16 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 3,689 hectares (36.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mossuril (3,716 ha, 1.1 %).
- What was the weather like?
- During the fire the temperature reached 32.8 °C, humidity dropped to 43 % and gusts hit 54 km/h. The fire danger index (FWI) reached 32, 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.
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.
Report an error
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. 261 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.
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.
