The winter temperature for UK coastal waters ranges from 8°C to 10°C, the south west peninsula being the warmest. Temperatures start to rise in the spring, reaching a summer maximum in the south west of about 17°C, but warmer in sheltered, shallow locations, especially during a warm summer.

Visitors to the UK are advised that a 'shortie' is advisable during the summer. In the winter, a full 'steamer' is recommended, boots, gloves and hood optional, depending on your bravado.
