Annecy has a humid continental climate with strong alpine influence — warm, sunny summers (daytime 22–28°C, but cool evenings 14–17°C), cold winters with limited valley snow but heavy snow on the surrounding peaks (most ski areas above 1,500m are reliable December–April).
What's the weather like in Annecy by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Annecy during May–Sep?
Patchy but improving — early April still has snow above 1,500m, the surrounding hills bloom in late April/early May, and the lake remains too cold for swimming. Easter brings a moderate crowd surge; the rest of spring is one of the lowest-tourist windows.
Shoulder season (Apr, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
