Tesker fire, March 2026 Tesker, Goudoumaria

Out · last detection 6 Mar 2026, 12:05 UTC

The fire started on 6 March 2026 in Tesker, Niger, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,084 hectares from heat detections, spread across 2 municipalities.

It is the 95th largest in Zinder since 2016 (of 103 with a page). Number 40 in Niger in 2026, of 48.

The power measured by the satellite is low (28.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

CAMS · Copernicus

On 4 March 2026 the air beside the fire reached 105 µg/m³ of PM2.5. That day averaged 76: 5.1 times the WHO daily guideline (15).

Frequently asked questions

How long did the Tesker fire last?
GWIS (Copernicus) dates it between 6 March 2026 and 6 March 2026: 1 day 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 1,084 hectares (10.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Tesker (924 ha, 0.0 %); Goudoumaria (159 ha, 0.0 %).
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Niger (OCHA COD-AB). 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 OCHA COD-AB (IGNN) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-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.
