Weather temperature and water temperature

There is a certain relationship between weather temperature and water temperature, but the regularity is difficult to grasp. For example, the water in a rice field is only a few centimeters, so the temperature is high and the water temperature is high. If the light is good for several days, the water temperature is even higher than the temperature.

The water in the swimming pool is ineffective because it is too deep.

If the water in the deep sea is calm, the water on the surface will also heat up when the temperature is high and the wind is low. But when the wind and waves are heavy, the temperature will not increase obviously, because the temperature is exchanged up and down. In the same way, it was not built in a day.
