Chilubi fire, 5 August 2026 Luwingu, Kasama, Chilubi

Out · last detection 25 Sept 2026, 11:57 UTC

The fire started on 5 August 2026 in Chilubi, Zambia, and satellites saw it burning for 52 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 68,523 hectares from heat detections, spread across 3 municipalities.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

Other fire pages in the same area and on the same dates:

Number 11 in Zambia in 2026, of 623.

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.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.7 mm on 2 Oct.

This area had burned before

97% of the perimeter overlaps earlier fires recorded since 2016: 29,621 ha in 2016, 25,742 ha in 2017, 15,151 ha in 2018, 32,085 ha in 2019, 25,976 ha in 2020, 29,126 ha in 2021, 30,392 ha in 2022, 20,102 ha in 2023, 21,702 ha in 2024, 26,332 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 66,520 ha that had burned before.

Frequently asked questions

How long did the Chilubi fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 5 August 2026 to 25 September 2026 (52 days). The perimeter dates it from 11 August 2026 to 18 September 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 68,523 hectares (685.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Luwingu (55,147 ha, 11 %); Kasama (14,537 ha, 1.4 %); Chilubi (1 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 32.3 °C, humidity dropped to 25 % and gusts hit 47 km/h. The fire danger index (FWI) reached 49, 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.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 9 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 11 August 2026 to 18 September 2026. 1,973 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.

How we build fire pages: methodology

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.
