Highland fire, 20 March 2025 Highland
The fire started on 20 March 2025 in Highland, United Kingdom, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 313 hectares from satellite imagery, spread across a single municipality.
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.
The power measured by the satellite is low (3.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 6.7 mm on 22 Mar.

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 22 March 2025 the air beside the fire reached 25 µg/m³ of PM2.5. That day averaged 15: 1.0 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Highland fire last?
- Copernicus dates it between 20 March 2025 and 21 March 2025: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 313 hectares (3.1 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Highland (306 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 14.7 °C, humidity dropped to 54 % and gusts hit 45 km/h. The fire danger index (FWI) reached 2, class Very low.
- 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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 7 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.
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.
