Roper Gulf fire, 24 October 2026 Roper Gulf
Out · last detection 6 Nov 2026, 04:46 UTC
The fire started on 24 October 2026 in Roper Gulf, Australia, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,976 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.
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.

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.

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 24 October 2026 to 6 November 2026 (14 days). The perimeter dates it from 25 October 2026 to 5 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,976 hectares (59.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Roper Gulf (6,005 ha, 0.0 %).
- Is the Roper Gulf fire still active?
- No fire detections since 6 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 39.2 °C, humidity dropped to 29 % and gusts hit 40 km/h. The fire danger index (FWI) reached 34, class 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.
Report an error
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 25 October 2026 to 5 November 2026. 124 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.
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.
