Overview
- Wednesday marks the national peak of the warm spell, with the South-West near the Pyrenees expected to exceed 25°C and Bayonne possibly reaching about 28°C.
- Several locations could approach or beat mid-November records, with forecasters highlighting Biarritz for unprecedented late-autumn consecutive warm days and potential highs near records in Paris, Le Havre and Bourges.
- Météo France has issued yellow wind alerts for about fifteen southern departments, warning of frequent 60–70 km/h gusts and peaks near 90 km/h in the Pyrénées and the south of the Massif Central, alongside rain from Languedoc to the Cévennes.
- Whether Wednesday or Thursday becomes the warmest day remains uncertain because cloud cover and Saharan dust could limit the maximum temperatures, though sunshine could push the felt temperature above 30°C in the South-West.
- After the midweek spike, very mild air shifts toward the east on Friday as the South-West starts to cool, with models pointing to a broader temperature drop of around 10°C by early next week.
