Magescq fire, September 2022 Magescq
The fire started on 17 September 2022 in Magescq, France, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 105 hectares from satellite imagery, spread across a single municipality.
It is the 12th largest in Landes since 2016 (of 13 with a page). Number 47 in France in 2022, of 49.
The power measured by the satellite is low (13.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Official record
According to BDIFF, a fire of 106 ha was recorded in Magescq on 16 September 2022 (the satellite measured 105 ha). The record has no coordinates, so it was matched by municipality and date.

The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions
- How long did the Magescq fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 17 September 2022 to 20 September 2022 (4 days). The perimeter dates it from 17 September 2022 to 18 September 2022.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 105 hectares (1.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Magescq (105 ha, 1.4 %).
- Did the fire reach a town?
- The fire started in Magescq and came within 5.4 km of its centre. 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 26.2 °C, humidity dropped to 18 % and gusts hit 35 km/h. The fire danger index (FWI) reached 27, class High.
- 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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 17 September 2022 to 18 September 2022. 18 Suomi-NPP VIIRS detections on those dates.
- Compared with BDIFF: 106 official ha against 105 ha of perimeter; they agree within 25%.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
