When do tourists visit Ascona?

Ascona is located in an area considered to be one of the sunniest regions in Switzerland. By March, Ascona already enjoys almost 200 hours of sunshine per month. That’s one reason Ascona attracts so many tourists year-round.

Considering I live north of Ticino, I’d recommend visiting Ascona after the ski season ends and right before the lakes warm up. I think it would be a great place to visit during autumn too, shortly before ski season begins.

As a result of its southern location, autumn, winter, and spring are milder in Ascona than in the rest of Switzerland. The climate of Ascona can be described as humid subtropical. Its summers are warm and humid. Winters are cold but milder than in the rest of northern Switzerland. Snowfall is also relatively low.

Best Time to Visit Ascona

The best time really depends on your plans and preferences. I would recommend April, May, June, September, and October. During these days, when the ski season is over and swimming season isn’t in full swing yet, flowers begin blooming or leaves change colors in Ascona.

The caveat is that it’s going to be more crowded and it may rain. As long as you avoid the main summer school holiday of July, it will be more comfortable for you.
