Swiss windsurfer Balz Müller has been chasing winter storms for quite a while, but what you’re about to witness is absolutely extreme.
On December 11, Switzerland’s Lake Uri was invaded by a dry, warm, and down-slope wind called foehn wind, resulting in powerful 120 km/h (75 mph) winds.
Müller and a small group of local windsurfers decided to give it a go. A decade ago, the 23-year-old sailor watched a video shot in Pointe Rouge, Marseille, and dreamed of riding a similar storm. So, this was his day.
