First, you practice laying out (while inside) wearing your newest tankini. It's too hot to lay out outside, so this will have to do.
Then, you get the pool water nice and warm and test it out with your hands.
Once you have determined the water is just right, pull all of your toys into the pool with you. They are probably hot too.
And if that's not enough to cool you off, you completely submerge yourself into the refreshing pool water!
After a nice, relaxing dip in the pool to cool off, you will be just right to dry off and take a nice nap....
