Lunte fire, 25 August 2026 Lunte, Kasama
The fire started on 25 August 2026 in Lunte, Zambia, and satellites saw it burning for 22 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 10,426 hectares from heat detections, spread across 2 municipalities.
It is the 73th largest in Northern since 2016 (of 628 with a page). Number 80 in Zambia in 2026, of 610.

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
99% of the perimeter overlaps earlier fires recorded since 2016: 2,242 ha in 2016, 4,928 ha in 2017, 2,797 ha in 2018, 5,162 ha in 2019, 3,197 ha in 2020, 4,193 ha in 2021, 6,719 ha in 2022, 4,334 ha in 2023, 3,990 ha in 2024, 3,421 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 10,355 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 5 September 2026 the air beside the fire reached 156 µg/m³ of PM2.5. That day averaged 72: 4.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Lunte fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 25 August 2026 to 15 September 2026 (22 days). The perimeter dates it from 25 August 2026 to 8 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 10,426 hectares (104.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Lunte (9,944 ha, 1.3 %); Kasama (542 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 30.0 °C, humidity dropped to 26 % and gusts hit 51 km/h. The fire danger index (FWI) reached 39, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zambia (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 4.0 (CC BY 4.0)). 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.
