It's been a while to feel coldness in the sea. I remember what our head of department said, seeing us riding a boat with only wet suit. "Oh, if you go inside the sea it will be cold~~" It is really cold Since it was short-sighted ( 3 meter ), I gave up taking sea photo. I was busy taking care of divers and checking their conditions. I guess the water will be warm soon. Nevertheless, diving is fun!!!
