Oldham fire, April 2025 Oldham, Kirklees
The fire started on 3 April 2025 in Oldham, United Kingdom, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 291 hectares from satellite imagery, spread across 2 municipalities.
This entry is probably a heather, gorse or hill-grazing burn, not a wildfire. In the UK and Ireland moors and hillsides are burnt every winter and spring to renew grazing or heather. This is our assumption, based on the time of year, ground with almost no woodland and the lack of news about this fire; it is not confirmed. That is why it is left out of the wildfire rankings.
We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

Where it burned
The weather it burned in
It had gone 5 days without rain (1 mm or more) when it started.
This area had burned before
83% of the perimeter overlaps earlier fires recorded since 2016: 240 ha in 2019, 33 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 241 ha that had burned before.

The smoke
CAMS · CopernicusOn 4 April 2025 the air beside the fire reached 20 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 291 hectares (2.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Oldham (207 ha, 1.4 %); Kirklees (83 ha, 0.2 %).
- What was the weather like?

- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of United Kingdom (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 and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 ADM3 (Open Government Licence v3.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
