Cold water swimming has become one of the fastest-growing coastal trends in the UK, and nowhere embraces it quite like Kent. These events take place across Christmas Day, Boxing Day and New Year’s Day, making Kent one of the best places in the UK for festive sea swimming.
This guide covers every major festive swim in Kent, including where they take place, what to expect, how cold the water really is, and how to take part safely.
Why Kent Is a Hotspot for Festive Sea Swims
Kent’s coastline is uniquely suited to winter swimming for several reasons:
- Easy access from London and the South East
- A strong and growing cold water swimming community
- A mix of sandy bays and sheltered areas
- Established traditions dating back decades
Events range from large organised charity dips to informal community gatherings, with many attracting hundreds of participants each year.
Key Dates for Festive Sea Swims in Kent
Festive sea swimming in Kent takes place across three main dates, each offering a slightly different atmosphere and scale.
- Christmas Day (25 December): informal, community-led swims
- Boxing Day (26 December): the largest organised charity event
- New Year’s Day (1 January): growing in popularity as a “fresh start” swim
While Boxing Day tends to attract the biggest crowds, New Year’s Day swims are becoming increasingly popular, particularly among regular cold water swimmers and wellness communities.
Sea temperatures during this period are typically between 6°C and 10°C, which feels extremely cold on entry and can trigger an immediate cold shock response.

On Christmas morning:
- Swimmers gather in groups, often wearing festive hats or costumes
- Some enter the tidal pool, while others go directly into the sea
