Lecumberry fire, 10 February 2023 Lecumberry
The fire started on 10 February 2023 in Lecumberry, France, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 128 hectares from satellite imagery, spread across a single municipality.
This record is most likely a pastoral burn (écobuage) in the Pyrenees, not a forest fire. In winter, grassland and scrub are burnt to renew the pasture, and this fire does not appear in France's official forest fire database (BDIFF). That is why it is left out of the fire rankings.
The power measured by the satellite is low (7.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 4.5 mm on 22 Feb.
This area had burned before
95% of the perimeter overlaps earlier fires recorded since 2016: 119 ha in 2019, 104 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 122 ha that had burned before.

Burnt area inside each municipality, from crossing the official 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.

Frequently asked questions
- How long did the Lecumberry fire last?
- Copernicus dates it between 10 February 2023 and 12 February 2023: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 128 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Lecumberry (128 ha, 2.2 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 5.9 km of Lecumberry. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 12.9 °C, humidity dropped to 36 % and gusts hit 31 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 France (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 ADM5 (Open Data Commons Attribution License 1.0). 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.
