Anyway, I said okay, let's get in. I was quite surprised that the water did not feel as cold as I was expecting. In short, we had a wonderful time, spending about an hour in the water, and it was really "quality family time". I never once felt cold. I am wondering if I really have to go to work tomorrow...
I live in canada here... saturday we played in the pool with 5 yo kid... the temp was 72... today 77 and it was perfect.
I know people north from here who use the pool all summer at 66-68. So don't worry, it's not dangerous when you are in the 70s
