A land breeze is set up along a coast when there is high pressure over the land and low pressure over the sea is explained below in complete details.

Explanation:

That means the air above the water is more heated, less compact, and commences to climb. Low pressure is generated above the water. Cold and compact air above the land starts to stimulate the water surface to substitute the warmer growing air. The cooling breeze from the land is denominated as a land breeze.
