Why is the wind direction at the seaside different during the day and at night? Explain from different angles of air pressure!

The specific heat capacity of the ground is different from that of the ocean, and the ground heats up faster than the ocean. Therefore, during the day, the ground temperature rises rapidly, the surface temperature is high, the air pressure is low, and the sea surface is relatively cold and the air pressure is high, thus forming an air pressure difference, and the wind will blow from the place with high air pressure to the place with low air pressure, so the wind will blow from the seaside to the land during the day.

At night, the land dissipates heat faster than the ocean, so the land is colder and the air pressure is higher, so the wind blows from the land with higher air pressure to the sea ~
