What are Land and Sea breezes?

The Land Breeze is a diurnal wind blowing from the land out to sea. It is caused by the differential cooling of land and sea. The cooling of the air over the land by radiation during the night causes the air to descend and flow seawards. Therefore during the night there is low pressure over the heated sea and high pressure over land. Hence, winds blow from land to sea during night.

The Sea Breeze develops along sea coasts or large inland water bodies in summer when the land heats much faster than the water on a clear day and a low pressure develops over the land. Under these conditions, in the day, the air blows from the sea to the land as there is high pressure on the sea and low pressure over the land.
