Mecula fire, 31 August 2026 Mecula

Out · last detection 4 Sept 2026, 22:57 UTC

The fire started on 31 August 2026 in Mecula, Mozambique, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,257 hectares from heat detections, spread across a single municipality.

It is the 284th largest in Niassa since 2016 (of 567 with a page). Number 273 in Mozambique in 2026, of 525.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

78% of the perimeter overlaps earlier fires recorded since 2016: 1,537 ha in 2016, 258 ha in 2018, 890 ha in 2019, 2,051 ha in 2021, 593 ha in 2023, 529 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,324 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.

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 Mecula fire last?
GWIS (Copernicus) dates it between 31 August 2026 and 4 September 2026: 5 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 4,257 hectares (42.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mecula (4,274 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 31.6 °C, humidity dropped to 29 % and gusts hit 36 km/h. The fire danger index (FWI) reached 38, 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.

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.
