What does the presence of a sea breeze indicate?

The presence of a sea breeze indicates cooler air coming from the ocean. This phenomenon occurs due to the differing rates of heating between land and water. During the day, land heats up more quickly than the ocean, causing the air above the land to become warmer and rise. This rising warm air creates a low-pressure area over the land, which is then filled by the cooler, denser air from over the ocean, resulting in a sea breeze.

The movement of this cooler air from the ocean towards the land brings a noticeable drop in temperature, making the area feel cooler, especially on hot days. This effect is particularly common in coastal areas during summer months when the temperature differences between land and sea are most pronounced. While the other choices might relate to atmospheric conditions to some extent, the most direct and defining characteristic of a sea breeze is the influx of cooler air from the ocean.
