Overview
- Météo‑France calls the episode “remarkable” for early November, with Wednesday’s national thermal index near 15°C versus about 11°C normally.
- Subtropical air lifted by the circulation of ex‑hurricane Mélissa south of Iceland is steering the mild air toward France and the British Isles.
- Daytime highs are set to reach around 20–24°C in many western and southern areas, with up to 25–27°C locally near the Pyrenees under foehn.
- Strong regional winds are expected in the south, with mistral and tramontane gusts reaching roughly 80 km/h in places.
- Showers are forecast to arrive on the Atlantic and southwest coasts Wednesday evening before spreading across much of the country Thursday, with a marked temperature drop in the southwest.
