An anticyclone in the Atlantic, off Ireland's coast, brings fresh air to the region, while stormy depressions circulate from Spain towards the Mediterranean, resulting in unsettled weather patterns across France. The northern half of the country is generally sunny and cool, while the southern regions face heavy and potentially violent storms.
Saturday's weather is marked by clearings in the morning, particularly in the northern half, with warm temperatures and sunny skies. However, the southern half experiences a more somber atmosphere with heavy, threatening conditions. Near the Mediterranean, low clouds cover the beaches due to the sea wind, while the Center-East experiences thunderstorms that could include hail. By the afternoon, the North-West enjoys seasonal temperatures with some wind on the beaches.
Violent thunderstorms may develop in the extreme South-West by Saturday evening, resulting in heavy rainfall and potential local flooding, particularly around the Hautes-Pyrénées, Pyrénées-Atlantiques, Landes, and Gers. Meanwhile, less intense thunderstorms are expected between Mâconnais and Franche-Comté, posing a threat to vineyards in these regions.
Sunday's weather doesn't bring much change, remaining unsettled and stormy from the South-West to the Center-East. The South-East sees a rapid spread of these conditions, leading to significant deterioration from the Mediterranean to the Alps. In the South-West, nighttime storms lower temperatures to around 15°C due to rain and wind, giving the region an autumnal feel. Meanwhile, the North-West enjoys pleasant, cool weather, albeit with the risk of sunburn due to the high sun at this time of year.
By Sunday afternoon, the unsettled weather spreads further across the South-East, with violent storms and heavy rainfall persisting in the mountains and the Alps. While the North-West experiences nice, cool weather, intermittent sunlight increases the risk of sunburn despite chilly winds along the Channel and the North Sea.
