Sea Breeze - Sea breezes occur during the daytime in warm sunny weather when the air over a land area is heated more rapidly than that over an adjacent water surface. As a result, the warmer air rises and relatively cool air from the sea flows onshore to replace it. At night, the air over the land cools faster than that over the nearby ocean and causes the air circulation to be in the opposite direction - a land breeze. Land breezes are usually weaker than sea breezes and have a less noticeable effect upon the temperature."
