Out · last detection 11 Nov 2025, 04:22 UTC

The fire started on 10 October 2025 in Croydon, Australia, and satellites saw it burning for 34 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 35,599 hectares from heat detections, spread across a single municipality.

It is the 157th largest in Queensland since 2016 (of 1742 with a page). Number 101 in Australia in 2025, of 1124.

It had gone 26 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 14 Nov.

This area had burned before

70% of the perimeter overlaps earlier fires recorded since 2016: 10,975 ha in 2016, 8,114 ha in 2017, 335 ha in 2020, 13,047 ha in 2021, 456 ha in 2022, 818 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 24,989 ha that had burned before.

How big is it?

It burned the equivalent of 22% of the area of London (356 km² against 1,583 km²).

Inside 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 Croydon fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 10 October 2025 to 12 November 2025 (34 days). The perimeter dates it from 16 October 2025 to 12 November 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 35,599 hectares (356.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Croydon (35,854 ha, 1.2 %).
What was the weather like?
During the fire the temperature reached 40.6 °C, humidity dropped to 7 % and gusts hit 44 km/h. The fire danger index (FWI) reached 63, class Extreme.
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 adjusted with the VIIRS detections inside the perimeter, which said 16 October 2025 to 12 November 2025. 840 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.

How we build fire pages: methodology ›

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.
