Why is it cooler in the summer near oceans and lakes, but warmer in the winter?

The warm air rises and the cooler coastal air moves in to replace it. Since the air is moving from the sea toward the land, this type of breeze is called a sea breeze. At night, the air inland cools down, and sometimes it cools down so much that it is cooler than the coastal air.

The answer would be abrasion.
