Two reasons:

1 - Convection (the warmer, lower density water stays on top)

2 - The sun - solar radiation heats the surface of the water and is absorbed, so it cannot penetrate deeper

Why is the ocean warmer at night?

Water retains heat longer than the air does. As a result, at night when the temperature drops the pool is fairly close to the temperature it was during the day while the air around it can become significantly colder. The same effect occurs with the ocean where the warmest ocean temperature on the eastern US are in September when the relative air around it is much colder. Pools seem warmer at night because the air outside (ambient air) is normally cooler. The temperature of the pool at the end of the day is when its the warmest and it cools down overnight. So ususually by morning the water is not as warm as it was when you get in earlier during the night.

Why are rivers cold in the summer and warm in the winter?

part of it is perception and part seasonal. As the temperature warms snow at the higher altitude begins to melt and flow into rivers and causes the rivers to be colder. When fall and winter come about the snow has all melted and the river has been heated by the sun making it warmer. Now for the perception part. As you are standing on the bank in the heat of summer the water feels cool and refreshing to your heated skin. In the winter your body feels colder so the temperature difference doesn't feel as extreme to your sense of touch making the water seem warmer than you remembered it being in the summer.
