A sea breeze is a natural wind that occurs along coastlines, typically during the day. It forms when the land heats up faster than the ocean, causing the air above the land to rise. This creates a low-pressure area over the land, while the cooler, denser air over the ocean moves in to replace it, resulting in a gentle breeze from the sea. Sea breezes are most common in coastal regions and can help moderate temperatures, making hot summer days more comfortable. They can also influence local weather patterns and contribute to the formation of clouds and precipitation, especially in areas like California and Florida.
