Overview
- Forecasts point to a turn on Wednesday, when sunshine spreads and temperatures lift after last week’s chill.
- Heat builds to a peak on Thursday and Friday, with 30°C or more in many areas and up to 35–36°C in the South-West according to the latest regional outlooks.
- Météo-France still expects very high local values, including about 31°C at Mont-de-Marsan in the Landes.
- The South-West bears the brunt while Provence warms more gently, with local offices calling for 25–27°C around Marseille, Aix and Avignon.
- High pressure over the Azores is steering hot air from Spain, and a nearby cold upper low could trigger thunderstorms over the Pentecost weekend even as the air stays warm.
