Traveller notes on Val d'Isère in August
Notes from nearby Annecy (84 km away)
Val d'Isère doesn't have its own notes for August yet — these are about Annecy, close enough to share the season.
Annecy's forum calls August normally hot and sunny, low-to-high 20s°C, though some years bring genuinely wet stretches. Regulars flag Alpine afternoon thunderstorms as a real possibility on the hottest days, and note evenings by the lake stay fresher thanks to a regular breeze — the lake itself is usually warm enough for a comfortable swim by early August.
Other months in Val d'Isère
Val d'Isère's forum calls January a safe bet for snow precisely because of its altitude — regulars list it alongside Tignes and Val Thorens as one of the high-altitude resorts where cover holds up even in years when lower resorts are struggling. Mountain passes like the Col de l'Iseran typically close for winter, so the drive in goes via Albertville and Bourg-Saint-Maurice; snow chains for the car are essential regardless.
