I like the look of the kiddie pool with the blue water, the palm trees around it and the gray rocks. I hope that water was warm to swim in and very clean. The parents could sit happily and watch their kids playing in the water.
Yes, that day the water was warm, since the sun is shining brightly. But it would be best that the kids dip on it in the afternoon where the sun is already setting. That way, the kids will not get sunburned and the parents, watching them too.
