When does a sea breeze typically occur?

A sea breeze typically occurs during the day due to the differential heating between the land and the water. During daytime hours, the sun heats the land more rapidly than the ocean, causing the air above the land to warm up and rise. This creates an area of lower pressure over the land. In contrast, the air over the cooler water remains denser and at a higher pressure.

As a result, the cooler, high-pressure air moves in from the ocean to replace the rising warm air over the land, creating a breeze. This phenomenon is most pronounced during the warmer months when the temperature difference between land and water is significant, leading to stronger breezes. Thus, the correct answer is when a sea breeze typically occurs during the day.
