Lucmau fire, November 2026 Lucmau, Callen

Out · last measured on 2 Nov 2026

The fire started on 2 November 2026 in Lucmau, France, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 142 hectares from satellite imagery, spread across 2 municipalities.

It is the 11th largest in Gironde since 2016 (of 13 with a page). Number 76 in France in 2026, of 115.

We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

It had gone 7 days without rain (1 mm or more) when it started. Rain came after the fire: 3.7 mm on 9 Nov.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 141 ha in 2020, 18 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 141 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.

Inside 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.

All of them had rain in the ten days after the end: the first rainy day brought a median of 4.4 mm.

It was considered over on 2 Nov, and on 9 Nov 3.7 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 17 of 17, with a median of 4.4 mm.

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 Lucmau fire last?
Copernicus dates it between 2 November 2026 and 2 November 2026: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 142 hectares (1.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Lucmau (140 ha, 2.1 %); Callen (2 ha, 0.0 %).
Is the Lucmau fire still active?
No fire detections since 2 November 2026. A lack of detections is not an official extinction.
Did the fire reach a town?
The fire came within 11.4 km of the centre of Callen, the closest of the areas it touched. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 13.9 °C, humidity dropped to 47 % and gusts hit 25 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.
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: 17. Their median duration was 2 days and their median area 144 ha; 0 % 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 4.4 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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. No Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
  • 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.

How we build fire pages: methodology

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.
