Land and sea breezes are basically caused by differential heating of the land and sea during the day and night, creating differences in local air pressure, thus inducing winds to blow in different directions.
During the day when the sun heats up the earth's surface, the land heats up much faster than the sea. Warm air above the land expands and rises. This creates a region of local low pressure. A sea breeze on the other hand remains comparatively cool and is a region of high pressure. A sea breeze thus blows in from the sea to the land. This is gentle breeze, best experienced along coastal districts in the tropics.
At night the reverse takes place as the land cools down much faster than the sea the cooler and denser air on the land creates a region of local high pressure. The sea on the other hand, conserves its heat and is relatively warmer than the land. The air over the sea expands and rises creating a region of local low pressure. A land breeze thus blows out from the land to the sea. Fishermen in the tropics often take advantage of the outgoing land breeze to sail out to sea.
