Cook fire, 24 August 2026 Cook
The fire started on 24 August 2026 in Cook, Australia, and satellites saw it burning for 28 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 17,229 hectares from heat detections, spread across a single municipality.
It is the 374th largest in Queensland since 2016 (of 1737 with a page). Number 165 in Australia in 2026, of 876.

This area had burned before
87% of the perimeter overlaps earlier fires recorded since 2016: 80 ha in 2016, 9,389 ha in 2017, 199 ha in 2018, 285 ha in 2019, 4,803 ha in 2020, 185 ha in 2021, 51 ha in 2022, 1,126 ha in 2023, 4,926 ha in 2024, 12,514 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 15,002 ha that had burned before.

What happened to each town
-
Cook where it started17,270 ha reached on 24 Aug0.2 %
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.

Frequently asked questions
- How long did the Cook fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 24 August 2026 to 20 September 2026 (28 days). The perimeter dates it from 24 August 2026 to 13 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 17,229 hectares (172.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Cook (17,270 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 32.2 °C, humidity dropped to 29 % and gusts hit 65 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 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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 24 August 2026 to 13 September 2026. 654 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.
