About the swim

An event with heritage…

Named as one of Britain’s top ten barmiest winter dips, TENBY’s famous Boxing Day Swim has been an institution in the small West Wales town for decades and last year featured in the ITV Wales series The Harbour, which was filmed in Tenby and shows a year in the life of the seaside community.

The Tenby Boxing Day Swim is organised by the Tenby Sea Swimming Association, which also stages the summertime Caldey Swim from the monastic island to the Tenby mainland.

The two events have enabled TSSA to raise nearly £300,000 for local, national and international charities and good causes over the years.

The 2022 Tenby Boxing Day Swim (our 50th) saw a record-breaking entry of  800 dippers taking  the plunge in the sunshine.

Swimmers can collect for their own good causes or the charities nominated by TSSA.

The 51st Tenby Boxing Day Swim takes place on the North Beach on Tuesday, December 26th 2023, from 11am.

The stampede for the sea is signalled at 11.30am, and swimmers can look forward to the warmth of the beach bonfire and hot soup on their return to the beach.

And to celebrate this special swim, the Mayor of Tenby will be handing out commemorative  medals.
