Mocuba fire, 16 August 2026 Mocuba, Derre
The fire started on 16 August 2026 in Mocuba, Mozambique, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 141,123 hectares from heat detections, spread across 2 municipalities.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

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 4 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 8 Sept.
This area had burned before
86% of the perimeter overlaps earlier fires recorded since 2016: 20,057 ha in 2016, 6,726 ha in 2017, 25,651 ha in 2018, 17,228 ha in 2019, 19,680 ha in 2020, 57,359 ha in 2021, 32,646 ha in 2022, 31,049 ha in 2023, 66,855 ha in 2024, 78,403 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 121,331 ha that had burned before.

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 89 hectares of built-up land and about 15,000 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 Mocuba fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 16 August 2026 to 14 September 2026 (30 days). The perimeter dates it from 21 August 2026 to 7 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 141,123 hectares (1,411.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Mocuba (104,889 ha, 12 %); Derre (37,113 ha, 7.8 %).
- What was the weather like?
- During the fire the temperature reached 35.7 °C, humidity dropped to 21 % and gusts hit 41 km/h. The fire danger index (FWI) reached 43, 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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 11 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 21 August 2026 to 7 September 2026. 6,732 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.
