Why swimming pools are cooler at midday and warmer in the afternoon?

Question

I’ve always wondered how come the water in a swimming pool exposed to the scorching midday summer sun feels cooler when you dive, say around 2-3 pm, and warm as tea around 7 pm when the sun has almost gone.

Answer 1

Because while at midday the sun is heating the most -> Change of temperature at its highest, later in the day The water has been exposed to more sunlight in total. -> absolute temperature at its highest.
