Raised going in 65 to 70 degree ocean water so it doesn't bother me. I like 75 degrees the best, cools your core temp down quickly. My pool was 84 today and I was not at all refreshed when I got out. Quickly was hot in the sun. Like getting out playing some horseshoes or ping pong working up a sweat then cooling off. Today was just gross for doing anything fun or productive outside. I don't know why anyone who spends most of the day outside prefers it.
