Tesker fire, 1 May 2026 Tesker

Out · last detection 2 May 2026, 12:58 UTC

The fire started on 1 May 2026 in Tesker, Niger, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,330 hectares from heat detections, spread across a single municipality.

It is the 29th largest in Zinder since 2016 (of 103 with a page). Number 10 in Niger in 2026, of 49.

The power measured by the satellite is low (21.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

CAMS · Copernicus

On 5 May 2026 the air beside the fire reached 64 µg/m³ of PM2.5. That day averaged 35: 2.3 times the WHO daily guideline (15).

Frequently asked questions

How long did the Tesker fire last?
GWIS (Copernicus) dates it between 1 May 2026 and 2 May 2026: 2 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 2,330 hectares (23.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Tesker (2,327 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.
