Mareeba fire, 18 May 2026 Mareeba

Out · last detection 28 May 2026, 15:44 UTC

The fire started on 18 May 2026 in Mareeba, Australia, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,781 hectares from heat detections, spread across a single municipality.

It is the 567th largest in Queensland since 2016 (of 1737 with a page). Number 244 in Australia in 2026, of 859.

The power measured by the satellite is low (27.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 8 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: 106 ha in 2016, 246 ha in 2017, 1,167 ha in 2018, 510 ha in 2020, 557 ha in 2021, 11,135 ha in 2022, 317 ha in 2023, 33 ha in 2024, 310 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 12,012 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.

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.

Frequently asked questions

How long did the Mareeba fire last?
GWIS (Copernicus) dates it between 18 May 2026 and 29 May 2026: 12 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 12,781 hectares (127.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mareeba (12,858 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 28.7 °C, humidity dropped to 19 % and gusts hit 45 km/h. The fire danger index (FWI) reached 32, class 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.

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.
