Overview
- Operational forecasts point to a peak on Wednesday and Thursday, with 20–25°C widely and locally 26–28°C near the Pyrenees under foehn conditions.
- Projected highs include about 25°C in Pau, 24°C in Biarritz, 22°C in Bordeaux and roughly 17–19°C in Paris, far above seasonal norms.
- Strong winds are expected through the sequence, often 40–60 km/h with gusts potentially reaching 80–90 km/h in the South on Friday, where orange alerts are not excluded.
- The warm spell is expected to fade from Friday as Atlantic fronts bring rain and a 5–8°C drop in parts of the country, returning conditions closer to normal over the weekend.
- Some November records could be approached or broken, though Saharan dust may limit solar heating, and meteorologists note these out‑of‑season spikes are becoming more frequent in a warming climate.
