If you’ve ever visited a beach on a hot day you may have found it to be windier by the sea than it is inland. Sea breezes are caused by convection currents.
What is a sea breeze?
Sea breezes occur on summer days because land heats up faster than the sea.
Warm air rises as it is less dense than cooler air. As the warm air rises, cooler air from over the ocean moves over land to take its place. It is this movement of warm and cool air that creates a sea breeze!
The opposite happens at night when the surface of land cools faster than the surface of water. The warmer air over the ocean rises and cooler land air flows out to sea to replace it.
