Powys fire, April 2022 Powys
The fire started on 25 April 2022 in Powys, United Kingdom, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 127 hectares from satellite imagery, spread across a single municipality.
It is the 20th largest in Wales since 2016 (of 25 with a page). Number 9 in United Kingdom in 2022, of 9.
We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

The smoke
CAMS · CopernicusOn 23 April 2022 the air beside the fire reached 18 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Powys fire last?
- Copernicus dates it between 25 April 2022 and 25 April 2022: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 127 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Powys (125 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 9.8 °C, humidity dropped to 55 % and gusts hit 34 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.

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.
