Chitambo fire, 7 September 2026 Chitambo
The fire started on 7 September 2026 in Chitambo, Zambia, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,536 hectares from heat detections, spread across a single municipality.
It is the 69th largest in Central since 2016 (of 401 with a page). Number 107 in Zambia in 2026, of 613.

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 23 days without rain (1 mm or more) when it started. Rain came after the fire: 3.0 mm on 1 Oct.
This area had burned before
85% of the perimeter overlaps earlier fires recorded since 2016: 2,608 ha in 2016, 1,757 ha in 2017, 1,333 ha in 2018, 4,131 ha in 2019, 2,324 ha in 2020, 1,871 ha in 2021, 1,138 ha in 2023, 512 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 7,214 ha that had burned before.

What happened to each town
-
Chitambo where it started8,600 ha reached on 7 Sept0.7 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 0.89 hectares of built-up land and about 100 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 5 September 2026 the air beside the fire reached 65 µg/m³ of PM2.5. That day averaged 36: 2.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Chitambo fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 September 2026 to 27 September 2026 (21 days). The perimeter dates it from 8 September 2026 to 20 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 8,536 hectares (85.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Chitambo (8,600 ha, 0.7 %).
- Is the Chitambo fire still active?
- No fire detections since 27 Sept 2026, 11:19 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 30.8 °C, humidity dropped to 28 % and gusts hit 53 km/h. The fire danger index (FWI) reached 36, class 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; 2 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 8 September 2026 to 20 September 2026. 192 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
