This end of the day, sunny and warm weather with some cumulus clouds, especially in the mountains. Calm, clear and soft evening, ideal for lingering outdoors, then a starry and soft night.
Sunday, very sunny weather until early afternoon despite some high sails and first cumulus clouds. Cumulus clouds getting bigger and bigger afterwards and a few showers and thunderstorms bursting over the reliefs before overflowing locally in the plains at the end of the day, especially in the Chablais. Rainy thunderstorm activity tending to become more widespread in the evening and at night. Warm temperatures during the day at all altitudes.
Expected temperatures in the Rhône plain: lows 14 to 16°, highs 29 to 31°. In resorts at around 1500m: lows 11 to 13°, highs 23 to 24°. On the summits: 12/19° to 2000m, 6/10° to 3000m.
Breezes sometimes moderate in the valleys and in the mid-mountains, moderate south-west in the high mountains. Gusts close to thunderstorm centres.
