Lourdios-Ichère fire, February 2025 Lourdios-Ichère, Sarrance, Arette
Out · last detection 6 Feb 2025, 13:17 UTC
The fire started on 6 February 2025 in Lourdios-Ichère, France, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 195 hectares from satellite imagery, spread across 3 municipalities.
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 (23.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Lourdios-Ichère fire last?
- Copernicus dates it between 6 February 2025 and 6 February 2025: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 195 hectares (2.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Lourdios-Ichère (112 ha, 6.9 %); Sarrance (83 ha, 1.8 %); Arette (0 ha, 0.0 %).
- Did the fire reach a town?
- The fire started in Lourdios-Ichère and reached its centre: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.
- What was the weather like?
- During the fire the temperature reached 12.0 °C, humidity dropped to 48 % and gusts hit 18 km/h. The fire danger index (FWI) reached 0, 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.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 30. Their median duration was 2 days and their median area 184 ha; 3 % went past 1,000 ha. All of them had rain in the ten days after the end: the first rainy day brought a median of 3.2 mm.
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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 12 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 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.
