How long did the Bidarray fire last?

Copernicus dates it between 18 February 2019 and 18 February 2019: 1 day 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 Bidarray (128 ha, 3.3 %).

Did the fire reach a town?

The closest fire to a town centre came within 3.2 km of Bidarray. 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 14.7 °C, humidity dropped to 40 % and gusts hit 45 km/h. The fire danger index (FWI) reached 6, class 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.

Bidarray fire, 18 February 2019 Bidarray

Out · last detection 18 Feb 2019, 12:51 UTC

The fire started on 18 February 2019 in Bidarray, France, and satellites saw it burning for 1 day. 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 (15.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
