Roper Gulf fire, 22 October 2024 Roper Gulf

Out · last detection 24 Nov 2024, 04:19 UTC

The fire started on 22 October 2024 in Roper Gulf, Australia, and satellites saw it burning for 34 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 77,838 hectares from heat detections, spread across a single municipality.

This entry is probably a savanna fire in Australia’s tropical north, not a bushfire like those in the south of the country. Millions of hectares of northern savanna and grassland burn every year: much of it in burns lit on purpose early in the dry season (traditional fire management, parks and cattle stations), the rest in grass fires that return to the same ground every few years. This is our assumption, based on the location; it is not confirmed. That is why it is left out of the wildfire rankings.

It had gone 34 days without rain (1 mm or more) when it started. Rain came after the fire: 15.4 mm on 25 Nov.

This area had burned before

55% of the perimeter overlaps earlier fires recorded since 2016: 1,419 ha in 2016, 1,800 ha in 2017, 21,658 ha in 2018, 5,474 ha in 2020, 22,041 ha in 2021, 354 ha in 2022, 2,409 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 42,583 ha that had burned before.

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 Roper Gulf fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 22 October 2024 to 24 November 2024 (34 days). The perimeter dates it from 22 October 2024 to 20 November 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 77,838 hectares (778.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Roper Gulf (78,265 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 41.2 °C, humidity dropped to 19 % and gusts hit 52 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 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; 7 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 22 October 2024 to 20 November 2024. 3,040 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.
  • Probably a vegetation burn: not counted in the totals.

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.
