Lourdios-Ichère fire, February 2026 Lourdios-Ichère, Sarrance
The fire started on 25 February 2026 in Lourdios-Ichère, France, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 283 hectares from satellite imagery, spread across 2 municipalities.
It is the 18th largest in Pyrénées-Atlantiques since 2016 (of 69 with a page). Number 34 in France in 2026, of 114.
The power measured by the satellite is low (6.8 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 4 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 27 Feb.
This area had burned before
98% of the perimeter overlaps earlier fires recorded since 2016: 105 ha in 2017, 191 ha in 2019, 255 ha in 2020, 190 ha in 2021, 238 ha in 2022, 218 ha in 2023, 205 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 277 ha that had burned before.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

People and buildings inside the perimeter
GHSL 2025Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 28 February 2026 the air beside the fire reached 30 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Lourdios-Ichère fire last?
- The official perimeter only gives the start date (25 February 2026). The end comes from the heat detections inside the perimeter: it burned until 27 February 2026 (3 days from 25 February 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 283 hectares (2.8 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Lourdios-Ichère (155 ha, 9.5 %); Sarrance (128 ha, 2.7 %).
- 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 20.0 °C, humidity dropped to 31 % and gusts hit 31 km/h. The fire danger index (FWI) reached 4, 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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 10 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
