Question 4

When is the best time to visit Walensee, Switzerland?

Accepted Answer

For the best underwater visibility, visit during the winter and early spring (December to April) when the water is clearest, often exceeding 15 meters. However, air and water temperatures are at their coldest. Summer offers more comfortable surface conditions for gearing up, but visibility can be reduced due to algal blooms and sediment from rivers. Autumn is a good compromise with decent visibility and moderate air temperatures.

Question 5

Visibility when diving in Walensee, Switzerland varies seasonally. It is typically at its peak during the winter months, from December to March, when it can often reach an exceptional 15-20 meters or more. During the summer, visibility usually decreases to around 5-10 meters because of snowmelt runoff, increased sediment, and algal blooms caused by warmer surface temperatures. Spring and autumn offer moderate conditions, generally in the 8-15 meter range.

Question 6

Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Walensee, Switzerland?

Accepted Answer

As a freshwater alpine lake, Walensee, Switzerland does not have large marine migrations like whale sharks or manta rays. The primary seasonal event for divers to observe is the fish spawning season.

This period offers a great opportunity to observe fish behavior and see them in larger numbers than usual.

The lake's ecosystem is more about subtlety than large, colorful reefs.
