Chobe fire, 25 September 2021 Chobe, Tutume
The fire started on 25 September 2021 in Chobe, Botswana, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 18,246 hectares from heat detections, spread across 2 municipalities.
It is the 15th largest in Chobe since 2016 (of 129 with a page). Number 33 in Botswana in 2021, of 406.

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
14% of the perimeter overlaps earlier fires recorded since 2016: 2,379 ha in 2018, 144 ha in 2019.

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.

Frequently asked questions
- How long did the Chobe fire last?
- GWIS (Copernicus) dates it between 25 September 2021 and 1 October 2021: 7 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 18,246 hectares (182.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Chobe (18,320 ha, 0.9 %); Tutume (77 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 36.1 °C, humidity dropped to 7 % and gusts hit 56 km/h. The fire danger index (FWI) reached 65, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Botswana (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 (Public Domain). 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.
