📋 Practical notes from the operator
- The same Sunday as Zurich's Samichlausschwimmen: both follow the first-Sunday-in-December rule.
- The «Freude herrscht» foundation gets children and young people into sport and exercise.
- According to Blausee AG the 6 December 2026 swim is fully booked; spectators are welcome (register or buy a ticket on the day). In 2025, 587 people swam at 4.7 degrees.
✨ What makes it special here
Forty-two metres sounds like nothing. At five degrees it is enough to take your breath away, and short enough that almost everyone makes it. That is the point: not a race against the clock, but a challenge with a purpose. The proceeds go to the «Freude herrscht» foundation, which gets children and young people into sport.
The date follows a rule: always the first Sunday in December, the same as Zurich's Samichlausschwimmen. In 2026 both fall on 6 December 2026: that Sunday, Switzerland has 900 places in cold water.

How we check
Every date comes from the organiser's, the municipality's or the canton's own site — never from an aggregator, never copied over from last year. Next to each source is the date we last read it.
Where only a fixed rule is published, such as the eve of St Nicholas' Day, we work out the date and label it “calculated from the fixed rule”. Anything not yet published stays open — we don't guess.
Something missing or changed? A note below is enough; we check it at the source.
