Land Breeze and Sea Breeze

     Return to Meteorology Index Page

A sea breeze occurs during the day when air is heated up quickly over the land and rises. This causes the slower heating seawater to produce less updrafts and the air flows inward towards the land to fill the missing rising air from the land creating a sea breeze.

A land breeze occurs during the night as the slower cooling seawater releases warm air and it rises. This rising causes the cooler air to flow from the land to the sea filling the rising air's place, creating a land breeze.
