Now you probably ask what about the weather?. Generally the Swiss mountain range and our Jungfrau region is in a tricky spot. We get hit by both weather patterns from the south and from the north. Jungfrau, Monch and Eiger work as a wall and in that regard each direction has unique patterns and storms are usually directed in the last moment when they reach high mountains. So what does that mean ? That weather is very unpredictable :).
Be prepared you can get nice warm days but you can as well get cold temperature and snow down to the valleys. That being said, these are let’s say once in a year events and are still considered as very unusual. Nice or let’s say reasonable weather when you are still able to do most of the activities is very common.
On average you get a perfect temperature – not too warm and not too cold. And this time of the year it is more about big weather patterns and these usually prevail for a few days. This means that the weather is a bit more stable in terms of sudden unexpected thunderstorms.
Summer– past years, the rising temperature caused very warm summer days to be more common. The number of days during summer which you call tropical is increasing. You can experience heat waves and lately they can be very persistent. One would say it’s sometimes too much for such a high alpine region. Just to put it into perspective – 20 years ago no air conditioning was needed in Interlaken.
But luckily for us, we have two beautiful lakes- Lake Brienz and Lake Thun, which are filled with glacier water, where you can always dip in to escape the heat.
One thing common in the summer especially in the Alpine regions with high mountains are thunderstorms. When there is a chance of thunderstorms appearing it will be visible in the forecast. This is the main danger especially if you are planning a trip or activities higher up on the mountain, because higher you are, the more severe weather you will experience.
If you go hiking alone, make sure you always have proper clothes and gear with you and check thunderstorm forecasts.
