Overview
- The late‑season warmth peaked Thursday with daytime highs around 26–30°C in parts of the South‑West, including Pau, Bordeaux and the Béarn.
- Forecasters say cooler air will begin arriving Friday, with roughly a 6°C fall in the South‑West followed by an additional drop of about 5°C over the weekend.
- A goutte froide, or cold upper‑level low, is forecast to cross the country this weekend and is likely to produce rain and locally heavy totals in the south‑east between Sunday and Monday.
- Snow is expected in the high mountains this weekend, with accumulations above about 2,500 metres in the Alps and the Pyrénées.
- The episode is expected to be brief with models projecting a rebound to above‑normal temperatures in parts of the west and south‑east early next week, but forecast confidence falls beyond that and heavy rain could disrupt travel and raise local flood risk in the south‑east.
