The term "sea breeze" refers to a wind that blows from over the sea towards the land. This type of wind is typically caused by temperature differences between the ocean and the nearby land, with the cooler temperatures of the water causing air pressure changes that result in the formation of wind. Sea breezes are most common during the daytime when the sun heats up the land more than the sea, creating a difference in temperature between the two. These breezes can be refreshing and provide relief from heat on hot summer days.
