Gabú fire, May 2026 Gabú

Out · last detection 13 May 2026, 14:32 UTC

The fire started on 6 May 2026 in Gabú, Guinea-Bissau, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,131 hectares from heat detections, spread across a single municipality.

It is the 107th largest in Gabú since 2016 (of 162 with a page). Number 51 in Guinea-Bissau in 2026, of 75.

The power measured by the satellite is low (16.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Gabú fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 6 May 2026 to 13 May 2026 (8 days). The perimeter dates it from 10 May 2026 to 13 May 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,131 hectares (11.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Gabú (1,137 ha, 0.4 %).
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Guinea-Bissau (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 (Open Data Commons Open Database License 1.0). 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.
