Mecula fire, 23 August 2026 Mecula
The fire started on 23 August 2026 in Mecula, Mozambique, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,260 hectares from heat detections, spread across a single municipality.
It is the 283th largest in Niassa since 2016 (of 567 with a page). Number 271 in Mozambique in 2026, of 525.

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 more than two months without rain (1 mm or more) when it started.
This area had burned before
90% of the perimeter overlaps earlier fires recorded since 2016: 1,122 ha in 2017, 1,270 ha in 2018, 1,592 ha in 2019, 1,330 ha in 2020, 1,815 ha in 2021, 626 ha in 2023, 614 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 3,836 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.

The smoke
CAMS · CopernicusOn 24 August 2026 the air beside the fire reached 30 µg/m³ of PM2.5. That day averaged 18: 1.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Mecula fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 23 August 2026 to 6 September 2026 (15 days). The perimeter dates it from 29 August 2026 to 6 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,260 hectares (42.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mecula (4,277 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 32.2 °C, humidity dropped to 29 % and gusts hit 40 km/h. The fire danger index (FWI) reached 38, 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.
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.
