Oceans, lakes, bays etc take a long time to heat up. That's why you could have a few days of really hot weather but the water is still cold. Once summer has set in and the water has had a month of hot weather and becomes quite warm, some evenings when the air is cool you can see the steam (misty) rising from the water. It happens in the morning as well. You get up early and because the air temp. is cool and the water is warm, a kind of mist is coming up off of the water.
By the end of summer, the body of water has heated to its maximum. Fall sets in and the daily temperatures are dropping but when you feel the lake or ocean water it feels warmer. Why?, because now that the water is warm it takes a long time to cool down.
This is important for cities on coastal areas. Their temperatures are moderated by large bodies of water. In the summer instead of being really hot they are just warm, because the breeze blowing over the water keep the coastal temperature down a bit. In the winter time, the water is warmer and the breezes blowing onshore keep the temperature from dropping way below freezing like they do in the cities in the interior.
Once water is warm it retains its heat much longer than solid things. Example sand on the beach. When it is hot the sand becomes so hot on your feet that it feels like it is burning. In the evening when the sun goes down the beach sand becomes quite cool to the touch. The water on the other hand will remain about the same temperature.

Water gains heat more slowly and loses it more slowly than the land. It does cool at night but no at the rate the land surface does. It will always try to hit the medium temperature. Lake waters stay warmer in the fall giving the area a longer growing season.

Water is a bad conductor of heat. Hence lake water heated up during the day time loses heat more slowly than the surrounding landmass. Hence it appears warmer. But by day-break, it gets enough time to cool down.
Again during the day time land warms up more quickly than the water, so the water appears cooler.

It depends on the humidity . With the humidity high it is hard to cool that much mass . So the change will be slow the higher the humidity.
