What impact do winds have on water temperature when blowing off shore?

When winds blow offshore, they often result in the cooling of surface water. This happens because the winds can increase evaporation rates from the ocean’s surface, which is a process that requires heat. As water evaporates, it takes energy (heat) from the surrounding water, thereby lowering the temperature of the remaining surface water.

Additionally, offshore winds can also contribute to the upwelling of cooler, deeper water to the surface. This phenomenon occurs when surface water is pushed away from the shore, allowing colder water to rise from beneath. The combination of increased evaporation and upwelling leads to a significant cooling effect on the surface water temperatures.

In contrast, winds that blow onshore generally lead to a warming effect, as they can cause warmer air to mix with the cooler water. However, the key factor in this question is the direction of the winds and their resulting effects on the water temperature when they blow offshore.
