Why does the wind blow off the ocean during the day at the beach, and off the land during the night?

Yikes, no! Pretty much every bit of that is wrong!During the day, the sun heats up both land and sea.
Sea heats up more quickly than land. This makes the air above the sea hotter than air above the land. Hence, air pressure at above sea is higher (pressure is directly proportional to temperature.) Air flows from higher to lower pressure, hence wind blows from land to sea.
During the night both sea and land cools down.
Sea cools down more quickly than land, making it colder than the land at night.
So, pressure is higher for air above the land because of higher temperature, and hence wind blows from land to sea.
The basic concept is that sea changes temperature more easily than the land.
