Overview
- Météo‑France confirmed a regional November record of 29.5°C on Wednesday at Aïcirits‑Camou‑Suhast (Pyrénées‑Atlantiques), with multiple south‑west stations near 29°C.
- Thursday brought another day of exceptional values, with widespread 20–27°C and early readings such as 22.9°C at 7 a.m. in Biarritz, far above seasonal norms.
- Météorologists cite a subtropical surge from the Sahara steered by the Atlantic low ‘Claudia,’ with the Foehn effect at the foot of the Pyrénées amplifying the warmth in valleys.
- Météo‑France placed numerous departments under yellow wind vigilance as gusts commonly reached 60–80 km/h and locally near 100 km/h, while Saharan dust reduced air quality and visibility in places.
- Forecasters expect a rapid pattern flip early next week to northwesterly/polar air, with temperatures dropping by roughly 8–10°C and the potential for lower‑altitude snow and the season’s first frosts.
