Roper Gulf fire, 12 October 2026 Roper Gulf

Out · last detection 9 Nov 2026, 04:46 UTC

The fire started on 12 October 2026 in Roper Gulf, Australia, and satellites saw it burning for 29 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 35,513 hectares from heat detections, spread across a single municipality.

We are reviewing this page: some of its data look inconsistent (the place, the dates or the area), so treat them with caution.

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.

GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

This area had burned before

14% of the perimeter overlaps earlier fires recorded since 2016: 1,194 ha in 2016, 2,896 ha in 2017, 1,142 ha in 2018, 1,784 ha in 2019, 138 ha in 2020, 1,214 ha in 2021, 287 ha in 2022, 368 ha in 2023, 1,741 ha in 2024, 675 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 4,985 ha that had burned before.

Residents< 20

Inside the perimeter there were about 0.16 hectares of 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 12 October 2026 to 9 November 2026 (29 days). The perimeter dates it from 12 October 2026 to 6 November 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 35,513 hectares (355.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Roper Gulf (43,109 ha, 0.2 %).
Is the Roper Gulf fire still active?
No fire detections since 9 Nov 2026, 04:46 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 39.4 °C, humidity dropped to 24 % and gusts hit 46 km/h. The fire danger index (FWI) reached 56, 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 12 October 2026 to 6 November 2026. 933 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
  • 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.
