It takes a huge amount of energy to raise the temperature of water and that usually comes from the sun. Then there’s night so some of the daily gain is continually lost.
Then, as already stated, evaporation takes away huge amounts of energy, but the temperature for changing from liquid to gas does NOT lower the temperature. This is a scientific law or concept called “heat of vaporization.”
The true reason water feels cooler on hot days is because it *is* cooler than the human body’s temperature. And water has a very high ability to “take heat away” in that situation. After all, it’s why water is used in radiators for cars and cooling nuclear reactors.
