Cook fire, 3 October 2025 Cook
The fire started on 3 October 2025 in Cook, Australia, and satellites saw it burning for 19 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 25,983 hectares from heat detections, spread across a single municipality.
It is the 219th largest in Queensland since 2016 (of 1737 with a page). Number 144 in Australia in 2025, of 1124.

The weather it burned in
It had gone 14 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 26 Oct.
This area had burned before
77% of the perimeter overlaps earlier fires recorded since 2016: 387 ha in 2016, 8,906 ha in 2017, 2,679 ha in 2018, 1,945 ha in 2019, 5,852 ha in 2020, 4,431 ha in 2021, 81 ha in 2022, 3,144 ha in 2023, 6,141 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 20,079 ha that had burned before.

What happened to each town

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 was no noticeable built-up land and almost nobody lived there (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 6 October 2025 the air beside the fire reached 27 µg/m³ of PM2.5, but no daily average passed the WHO 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 Cook fire last?
- GWIS (Copernicus) dates it between 3 October 2025 and 21 October 2025: 19 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 25,983 hectares (259.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Cook (26,044 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 34.9 °C, humidity dropped to 30 % and gusts hit 61 km/h. The fire danger index (FWI) reached 40, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Australia (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 from the perimeter: the VIIRS detections inside it did not change them. 746 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 International (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.
