Having a good time in the water is easy, but don't forget to practice water safety too. Make sure you've got what you need to stay prepared and safe whether you're on a boat, at the pool or hanging at the beach.
When I try to get into the pool, if that water is cold, I'll admit it. I'm a 'one inch at a time' kind of guy. First the feet. After about a half hour, when they warm up, I'll put the lower leg in and so on. The whole process takes about three and a half hours.
