July Rain In Alps - Are Certain Regions Less Rainy?

This is a great site for historic weather conditions. I plugged in for Murren last July.

Thank you Marc! It appears that there is a good chance we will encounter rain in July.

We want to avoid being cooped up inside for consecutive days with two restless teenagers. Our primary purpose in traveling to the area is to experience the alps by hiking, etc.

Our considerations are as follows:

1. Should we choose a larger alpine town that may offer some indoor activities as a backup plan on rain days? Do they exist? If so, which town may be the best choice?

2. Should we choose a shorter stay in one of the small villages (3-4 days rather than 7-8) and bring appropriate rain gear and venture out regardless of rain, rather than a longer stay where we plan to wait for good days and may end up being stuck indoors on rainy days?

Thank you!

A day with rain is not necessarily a "rainy day". The weather is highly changeable!
This said, if you are planning to stay for a full week, maybe look into renting a vacation home/flat? That way, if you do have to stay indoors, you have more space to do so.

Seconding Balso's comment - it's not impossible to get a string of rainy days, but most of the time, "rain" in the mountains in the summer means it will rain heavily for just a couple of hours, often thunderstorms in the late afternoon when the clouds have built up. Basically you just have to closely follow the weather reports and normally plan on doing hiking and outdoor activities earlier in the day. Definitely bring some rain gear anyway just in case.

If you are unlucky, the Berner Oberland region probably offers the most 'rainy day' alternatives: you could visit the Trümmelbach waterfalls in Lauterbrunnen, go into Bern for a day trip, visit one of indoor ropes courses or climbing facilities in the area or go to Interlaken and do a make-your-own-chocolate class. Some hotels up in the mountains also have game rooms with foosball, pool or ping-pong tables, board games etc so maybe you want to check for that.

To your original question, yes some areas of the Alps are rainier than others. The northwestern parts in particular. Southern parts and southern slopes are dryer, either because they are geographically farther from the common storm track, and/or are rain shadowed by high crests to the north.
Voralburg east of Lake Constance can be quite wet because it's exposed. Much of Switzerland is rain shadowed by its own high mountains, but the Berner Oberland is fairly open to the northwest.

Also note that in summer thunder shower activity can come from the south and affect Southern areas and slopes fairly intensely. I've done a lot of all day bicycle rides in the Alps in summer, and more than once have had the experience of riding in full blast shower levels of downpour. Mountains gonna mountain!

Because of the pent- up demand for travel this summer, many folks here are reporting that moderately priced lodging is filling up fast. I'd advise you draft an itinerary asap and start booking lodging.
Have a great trip in this beautiful country.,
