Barkly fire, 1 October 2025 Barkly

Out · last detection 10 Oct 2025, 04:22 UTC

The fire started on 1 October 2025 in Barkly, Australia, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 100,607 hectares from heat detections, spread across a single municipality.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

It is the 57th largest in Northern Territory since 2016 (of 3493 with a page). Number 23 in Australia in 2025, of 1124.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

55% of the perimeter overlaps earlier fires recorded since 2016: 5,987 ha in 2017, 1,962 ha in 2022, 53,007 ha in 2023, 1,242 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 55,495 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Barkly fire last?
GWIS (Copernicus) dates it between 1 October 2025 and 10 October 2025: 10 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 100,607 hectares (1,006.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Barkly (100,829 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 38.8 °C, humidity dropped to 6 % and gusts hit 62 km/h. The fire danger index (FWI) reached 81, class Very 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.

Emergency number: 000

Satellite cross-check

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 000.

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.
