Overview
- Météo-France confirmed 29.5°C at Aïcirits-Camou-Suhast in the Pyrénées-Atlantiques, setting a November record at the station and marking the peak of the episode.
- Temperatures ran 5–10°C above seasonal norms, with 25–29°C widely in the South-West and around 20–21°C reaching into central and northern regions.
- The setup features very mild subtropical air drawn north by Atlantic depression Claudia and a central European high, with a Foehn effect boosting warmth along the Pyrénées.
- A Saharan dust plume is tinting skies and reducing air quality from the South-West toward the Paris area, while strong southerlies have prompted yellow wind alerts in multiple departments.
- Forecasts point to an abrupt cool-down early next week with an 8–10°C drop, the first widespread frosts and mountain snowfall returning after the late-autumn spike.
