Summers in phoenix arizona are hot (125 f is not uncommon), and dry. if you hop into an outdoor swimming pool on a summer day in phoenix, you will find that the water is too warm to be very refreshing. however, when you get out of the pool and let the sun dry you off, you find that you are quite cold for a few minutes.

Explanation:

when we get out of the water we feel quite cold due to the latent heat of evaporation of water.

Water at our body gets converted into gas and leaves behind the cooling effect which makes us feel cold.

While when we are inside the pool we are in constant touch of water, therefore, we get the warmth of the water and it becomes difficult to bear it.
