Sanggau fire, July 2024 Sanggau
The fire started on 25 July 2024 in Sanggau, Indonesia, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,998 hectares from heat detections, spread across a single municipality.
It is the 161th largest in West Kalimantan since 2016 (of 267 with a page). Number 6 in Indonesia in 2024, of 16.
We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Where it burned
The weather it burned in
It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 18.8 mm on 30 Jul.
This area had burned before
98% of the perimeter overlaps earlier fires recorded since 2016: 298 ha in 2016, 212 ha in 2017, 267 ha in 2018, 523 ha in 2019, 1,254 ha in 2020, 1,141 ha in 2022, 1,058 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,965 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 25 July 2024 the air beside the fire reached 47 µg/m³ of PM2.5. That day averaged 25: 1.7 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Sanggau fire last?
- GWIS (Copernicus) dates it between 25 July 2024 and 28 July 2024: 4 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 1,998 hectares (20.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Sanggau (2,012 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 33.9 °C, humidity dropped to 53 % and gusts hit 23 km/h. The fire danger index (FWI) reached 10, class Low.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Indonesia (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.
Emergency number: 112

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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
