Winds associated with a high pressure system blow slightly outward from the center and in a clockwise fashion. A Dutch meteorologist named Buys Ballot formulated a technique in 1857 to determine the location of pressure centers. With your back to the wind, pressure to your left is lower. In the Southern Hemisphere, the opposite is true. The sea breeze is a classic example of the thermal-pressure relationship.
Sea breezes occur when the land mass next to the water area heats up at a much greater rate.
This results in lower pressure over land while pressure over water is higher. The sea breeze is the ensuing flow of air from high to low pressure. The strength of the sea breeze depends upon the difference between the temperature of the water and the adjacent coastal area. At night, the land cools more quickly than the water resulting in a reversal of wind flow from land to water. The foehn wind is unlike the sea breeze in that it is observed only in mountain areas.
