When might a sea breeze be particularly strong?

A sea breeze is particularly strong during warm, sunny days due to the temperature difference that develops between the land and the ocean. When the sun heats the land, it warms the air above it, causing that air to rise. This action creates a lower pressure area over the land. In contrast, the ocean retains its heat more effectively and remains cooler than the heated air above the land. The cooler, denser air over the water then moves in to replace the rising warm air, creating a breeze from the sea toward the land. This effect is most pronounced on warm, sunny days when the temperature differential is greatest, leading to a more vigorous sea breeze.

This phenomenon is less pronounced during heavy rainfall, at night when land temperatures drop, and in the winter months when temperature differences between land and ocean are often diminished. Heavy rainfall tends to stabilize the atmosphere, reducing the temperature contrasts necessary for a strong breeze. At night, the land cools more rapidly than the sea, which can lead to a land breeze instead. In winter, cooler air over both the land and the sea may not allow for sufficient heating of the land to create a strong sea breeze.
