How to Prepare for Your First Open Water Swim
Preparation is key. Start by researching your swim spot, checking for currents, entry and exit points, and local advice. Wear a brightly coloured swim cap and bring a tow float for visibility and buoyancy.


Acclimatising to Cold Water
UK waters are often colder than expected. Ease in gradually, focus on controlled breathing, and stay calm. Simply Swim have a range of thermal swimsuits suitable to keep you warmer while swimming.

‘Float to Live’ – The RNLI’s Life-Saving Rule
If you get into difficulty, don’t panic. Float on your back with arms and legs spread. Control your breathing and call for help. It sounds simple, but this technique has saved lives. Learn more about it in our featured video.

What is the ‘After Drop’?
After a swim, your core temperature continues to drop even once you’re out of the water. This is the ‘After Drop’. Dry off immediately, change into warm layers, and have a hot drink ready. A Dryrobe Advance is perfect for fast warming and protection post-swim.

Swim Safe, Swim Smart
Open water swimming is deeply rewarding—but only when done safely. Equip yourself with the right knowledge and kit, and you’ll enjoy every swim with confidence.
