I'm gonna open my pool next Monday.
It will still be too cold for V to swim, but I like it very cold. (I don't have a heater in mine, wouldn't want one)
By August the water is a little warm for me.
Enjoy. You're gonna love it. If you have kids you won't be able to keep them out of it.
I don't have any at home, so I can enjoy mine in peace.
