Notes:
Land heats and cools more frequently than the sea. During the day time, the land gets heated and the air over the land being hotter and lighter than that over the sea, a low-pressure area is created over the land. The hot air rises and cool air from the sea reach in towards the land, which is referred to as the sea breeze. During the time of night, the land rapidly loses its heat faster than the sea. The air over the sea is, therefore, warmer and lighter than over the land and a breeze blows but from the land towards the sea.

Notes:
The southwest monsoon brings rains towards the end of summer. It’s the temperature variation between the sea and the landmass – sea air being cooler and land being warmer – that causes the action of wind force. Also, the Temperature Gradient which is the temperature variation between the landmass and the surrounding sea is responsible.
