Broome fire, 1 May 2026 Derby-West Kimberley, Broome

Out · last detection 8 May 2026, 17:00 UTC

The fire started on 1 May 2026 in Broome, Australia, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,390 hectares from heat detections, spread across 2 municipalities.

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.

It had gone 36 days without rain (1 mm or more) when it started.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 20 ha in 2016, 172 ha in 2017, 115 ha in 2018, 2,418 ha in 2019, 1,884 ha in 2020, 4,927 ha in 2021, 13 ha in 2022, 3,377 ha in 2023, 733 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 6,971 ha that had burned before.

How big is it?

It burned the equivalent of 4.7% of the area of London (74 km² against 1,583 km²).

Frequently asked questions

How long did the Broome fire last?
GWIS (Copernicus) dates it between 1 May 2026 and 7 May 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 7,390 hectares (73.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Derby-West Kimberley (6,912 ha, 0.1 %); Broome (528 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 35.5 °C, humidity dropped to 15 % and gusts hit 53 km/h. The fire danger index (FWI) reached 90, 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.

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.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 166 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.
  • 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.
