365 Brave Souls Plunge into Icy Limmat River in Zurich’s Annual Santa Claus Swim
Published: December 7, 2025, 7:00 PM EST | Zurich, Switzerland – archyde.com
Zurich’s annual Santa Claus Swim unfolded today, defying both rain and frigid temperatures as 365 determined swimmers took the plunge into the Limmat River. The event, a beloved local tradition, saw participants dressed as everything from angels to, naturally, Santa Claus, braving water temperatures of just 8 degrees Celsius (46 degrees Fahrenheit).
A Tradition Takes a Dip – and a Farewell
The swimmers embarked on a 111-meter (approximately 364 feet) swim from Pier 7 at Bellevue to the Frauenbadi, battling the current. For the particularly adventurous, an optional 125-meter loop extended the challenge. But today wasn’t just about the cold; it marked a significant moment for the event’s founder, Stefan Weiss, who participated in his final official swim.
Weiss, who founded the Santa Claus Swim, is stepping down after years of organizing the event. He plans to continue swimming in future years, but is handing over the logistical reins to a new team. “It’s time for a new chapter,” Weiss commented, wrapped in a bathrobe after his swim. “But the spirit of the swim will continue.”
The Perils of the Plunge: Cold Water Safety
The initial moments in the icy water are the most critical, according to lifeguards on duty. The shock of the cold can disrupt circulation, posing a risk to swimmers. Fortunately, no incidents were reported this year, thanks to the vigilant presence of safety personnel. This event highlights the growing popularity of cold water swimming, a practice gaining traction for its purported health benefits – but one that demands respect and preparation. Experts recommend acclimatizing to cold water gradually and always swimming with a buddy.
More Than Just a Swim: A Charitable Cause
Beyond the spectacle and the challenge, the Santa Claus Swim serves a vital purpose: fundraising for charity. This year, the event raised over 7,000 Swiss francs for Hope Leman, an organization that provides sailing experiences for children recovering from cancer. The funds will help these children find healing and joy on the water.
First-Timers and Seasoned Veterans
Among the swimmers was Jenny Wyss from Aargau, participating in her first Santa Claus Swim. “I thought I needed a new challenge,” she said, admitting the water was “extremely cold, so cold that my skin burned.” She’s already planning her return next year. Alongside the newcomers were seasoned veterans like Roger Bartholdi, a local councilor who has participated in all 24 Santa Claus Swims, always in full Santa gear. “It’s most beautiful when it snows,” he reminisced, “but that only happens rarely.”
The Santa Claus Swim is a testament to the human spirit – a willingness to embrace a challenge, support a good cause, and find joy even in the face of freezing temperatures. It’s a uniquely Zurich tradition that continues to inspire and uplift.
For those seeking similar invigorating experiences, numerous organized cold water swimming groups are emerging worldwide. Researching local groups and prioritizing safety are crucial steps for anyone considering taking the plunge. The enduring appeal of this Zurich tradition reminds us that sometimes, the coldest challenges yield the warmest rewards.
