Broome fire, 27 April 2026 Broome, East Pilbara
The fire started on 27 April 2026 in Broome, Australia, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 19,008 hectares from heat detections, spread across 2 municipalities.
It is the 384th largest in Western Australia since 2016 (of 2718 with a page). Number 142 in Australia in 2026, of 859.

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.
The weather day by day
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.

The smoke
CAMS · CopernicusOn 29 April 2026 the air beside the fire reached 30 µg/m³ of PM2.5. That day averaged 16: 1.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Broome fire last?
- GWIS (Copernicus) dates it between 27 April 2026 and 29 April 2026: 3 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 19,008 hectares (190.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Broome (10,555 ha, 0.2 %); East Pilbara (8,580 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 32.7 °C, humidity dropped to 24 % and gusts hit 39 km/h. The fire danger index (FWI) reached 43, class Very 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.

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.
