Winter Swimming

Winter Swimming Registration

Thanks for coming to the website to find out more about winter swimming, please read on to find out more about temperatures, tips and what potential risks you’ll need to know about.


During the summer the water will usually be above 17 degrees Celsius. Winter swimming is recommended when the water is between 12 and 16 degrees Celsius. The water will feel reasonably colder than it would during the summer but when you’re wearing your wet suit and over-suit you’ll get used to it in no time.


Swimming in cold temperatures can hold many risks. When you enter the water you body will start losing heat and this can make you feel uncomfortable. The effects of the cold can be moderated by wearing a wetsuit and oversuit but also by acclimatising your body. Acclimatising is a way of getting your body used to the cold temperatures and this is done by swimming in the cold water regularly i.e. at least once a week.

Tips for Cold Water Swimming

1. Getting in the water is the first step to acclimatising your body to the cold temperatures and it’s recommended that you get in as soon as you can. Once you’re in you should wait for between 1 and 2 minutes to allow your blood circulation to get going.

2. When you first get in the water you may feel breathless. This is normal as your chest contracts in the cold water. To overcome this, exhale as you jump in.

3. The most important thing to do is not stay still for too long. The best way to warm up will be to start swimming.

We’ll need some quick details from you to figure out what size over-suit we’ll need to provide for you (free of charge) and we’ll also need a few other details so that we can register your interest. Once we have enough people signed up we’ll let you know what times the swimming sessions will take place.

Remember: When you come to swim in the winter with us you’ll need a wet suit. You won’t normally be able to swim in just a normal bathing suit. The wet suit will provide extra warmth and is recommended when swimming in temperatures less than 14 degrees Celsius. However, if you feel the weather, and your exposure experience is such that you do not need a wetsuit, then you must swim towing a buoyancy float to support you in the event of experiencing cramp or other problem, until rescue assistance arrives.
