Western France has been experiencing 35 consecutive days of heavy rain, the longest rainy streak since records began in 1959, according to the national weather service Meteo-France.
The Bordeaux region was among the worst hit by the torrential rainfall, with water levels rising in various rivers and causing widespread flooding.
This multi-temporal radar image uses information from two separate acquisitions captured by the Copernicus Sentinel-1 mission on 6 and 18 February 2026 to show in red the extent of the flooding across the region.
In response to the devastating floods, the Copernicus Emergency Management Service has been activated to produce detailed maps of the affected areas.
With its ability to penetrate cloud cover and frequent revisit times, Copernicus Sentinel-1 is ideal for flood monitoring, enabling the assessment of flood extent and its impact on people and the environment.
