Lufwanyama fire, June 2026 Chingola, Lufwanyama
Out · last detection 15 Jul 2026, 11:24 UTC
The fire started on 21 June 2026 in Lufwanyama, Zambia, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,886 hectares from heat detections, spread across 2 municipalities.
Number 237 in Zambia in 2026, of 621.
GWIS near-real-time perimeter, from the layer that changed in August 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.
The power measured by the satellite is low (21.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

55% of the perimeter overlaps earlier fires recorded since 2016: 980 ha in 2016, 7 ha in 2017, 742 ha in 2018, 1,439 ha in 2019, 5 ha in 2020, 1,445 ha in 2021, 88 ha in 2023, 1,097 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,705 ha that had burned before.

Frequently asked questions
- How long did the Lufwanyama fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 21 June 2026 to 15 July 2026 (25 days). The perimeter dates it from 24 June 2026 to 8 July 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,886 hectares (48.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Chingola (2,558 ha, 1.5 %); Lufwanyama (2,355 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 27.9 °C, humidity dropped to 27 % and gusts hit 41 km/h. The fire danger index (FWI) reached 42, 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.

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.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 24 June 2026 to 8 July 2026. 143 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
