Land breeze is a local wind that blows from land to sea, typically at night or in the early morning. It occurs due to the difference in temperature between the land and the sea.

During the day, the sun heats the land more quickly than the sea. As a result, the air above the land becomes warmer and less dense than the air above the sea. This creates a pressure gradient, with higher pressure over the sea and lower pressure over the land. The resulting wind blows from the higher-pressure area (the sea) to the lower-pressure area (the land). This is known as a sea breeze.

At night, the land cools more quickly than the sea. This causes the air above the land to become cooler and denser than the air above the sea. This reverses the pressure gradient, so that the higher pressure is now over the land and the lower pressure is over the sea. The wind then blows from the higher-pressure area (the land) to the lower-pressure area (the sea). This is known as a land breeze.

Land and sea breezes are typically most noticeable in coastal areas, where the difference in temperature between the land and the sea is greatest. They can also be affected by other factors, such as the terrain and the prevailing winds.
