May or June 2024 for Swiss travel

Think the June dates are the best - that’s when I go for hiking around Lauterbrunnen… before the big crowds and hot weather.

June as lot of trails at higher elevations are not open in May as it is too muddy snowy to hike.

I was originally planning for May myself and learned that some of the trails would not be open and that muddy trails were also likely at that time. I would definitely go with June or early September.

June. We were there in late June and some trails had just opened due to the amount of snow. If you go in May, you may still have some closures.

As for weather, you have to be prepared for everything. We had clouds and some rain in late June for a part of the day for 5 of the 6 days we were there. Keep your schedule flexible and go where weather dictates. When it was cloudy in Wengen, we went to Lake Brienz. When it was rainy, we went to Tummelbach Falls. When we got a clear morning, we went to Jungfraujoch. We did get caught in a heavy rainstorm while we were on the First mountain carts and were delayed getting down the mountain when lightning shut down the gondolas. We were just thankful we weren’t IN one of the gondolas at the time!

I have been there every month from April to September and I think the sweet spot is June.

I agree with Nigel. June can be sunny or rainy as can be every month from April-Oct. June is usually nice but not to hot. Crowds are less than July and August. Weather there can change fast from day to day and even hour to hour. My other sweet spot is Sept 10-Sep 20th. I have had real good luck with sun then and smaller crowds for trains and restaurants and some hotels start to reduce prices a little then.

One other thing. Schilthorn is usually sunny in the early morning and crowds are less but again unexpected clouds can roll in or leave.
