  • What time does the swim start?

    The first wave will take place at 4pm. 

  • How warm will the water be?

    We expect the water to be between 17 and 20 degrees C at the end of September

  • Do I have to wear a wetsuit?

    Wetsuits are not compulsory. The water is currently around 17 degrees, and may get a little cooler. If you are not acclimatised to swimming in cold water without a wetsuit, we recommend that you wear one.

    If you wish to hire a wetsuit, we have an arrangement with a wetsuit supplier who will be supplying Orca open water suits, at a reduced rate of £10 /wk, £5 on the day rate (booked in advance).
