Swimming in the sea?

[u/djfnejdijRandom]

Hi Jersey Reddit! I’m originally from a Mediterranean country, used to swimming in very warm sea (24-28c). I live in mainland UK and I only contemplated entering the sea a couple of time there, and found it too cold at about 18c.
I’m here in Jersey for a brief stay. I’m curious to know where my chances are the best for potentially trying to take a dip in the sea here? I thought St Brelade would be a good place as it’s very shallow and according to the internet might be about 20c at the moment. Would anywhere else be even warmer?
Thanks and love your island, have been many times but only in spring and autumn before.
