Broome fire, 12 August 2026 Broome

Out · last detection 18 Aug 2026, 05:23 UTC

The fire started on 12 August 2026 in Broome, Australia, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 24,783 hectares from heat detections, spread across a single municipality.

It is the 249th largest in Western Australia since 2016 (of 2729 with a page). Number 109 in Australia in 2026, of 891.

It had gone 34 days without rain (1 mm or more) when it started.

This area had burned before

43% of the perimeter overlaps earlier fires recorded since 2016: 2,776 ha in 2017, 1,072 ha in 2018, 998 ha in 2020, 2,888 ha in 2022, 2,891 ha in 2023, 334 ha in 2024, 1,107 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 10,654 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 16% of the area of London (248 km² against 1,583 km²).

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 2025
Built-up area0.36 ha
Residents< 20

Inside the perimeter there were about 0.36 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 Broome fire last?
GWIS (Copernicus) dates it between 12 August 2026 and 18 August 2026: 7 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 24,783 hectares (247.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Broome (24,696 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 32.7 °C, humidity dropped to 22 % and gusts hit 62 km/h. The fire danger index (FWI) reached 60, 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.

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.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 432 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.

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.
