Barkly fire, 14 October 2025 Barkly, Roper Gulf
The fire started on 14 October 2025 in Barkly, Australia, and satellites saw it burning for 31 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 67,364 hectares from heat detections, spread across 2 municipalities.
It is the 115th largest in Northern Territory since 2016 (of 3508 with a page). Number 46 in Australia in 2025, of 1124.

The weather it burned in
It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 3.6 mm on 14 Nov.
This area had burned before
68% of the perimeter overlaps earlier fires recorded since 2016: 1,478 ha in 2016, 32,415 ha in 2017, 518 ha in 2018, 435 ha in 2021, 27,264 ha in 2022, 7,823 ha in 2023, 750 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 45,825 ha that had burned before.

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.

The smoke
CAMS · CopernicusOn 23 October 2025 the air beside the fire reached 62 µg/m³ of PM2.5. That day averaged 27: 1.8 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Barkly fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 14 October 2025 to 13 November 2025 (31 days). The perimeter dates it from 17 October 2025 to 13 November 2025.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 67,364 hectares (673.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Barkly (47,242 ha, 0.2 %); Roper Gulf (20,185 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 41.0 °C, humidity dropped to 6 % and gusts hit 49 km/h. The fire danger index (FWI) reached 66, 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 17 October 2025 to 13 November 2025. 1,377 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.
