Why does it get windy?

Answer 1

The beach lies at the interface of the ocean and the land. These two bodies heat and cool at very different rates, and this unequal heating/cooling of the air causes the local coastal winds.

As distinct from the meteorological winds, which are caused by upper atmosphere conditions.

This is called the transmission of heat (Convection currents produced by sea breeze and land breeze).

Sea and land breezes

On a hot day, the land heats up faster than the sea. Hot air over the land rises. This hot air is replaced by cold, denser air from the sea. This produces a breeze from the sea to the land. The breeze is called a sea breeze.

At night, the land cools quicker than the sea. The hot air over the sea rises. Cold air from the land replaces the hot air. This produces a land breeze.

Answer 2

it is often windy at the beach because in the day heat rises from the land and so the heat from over the sea comes in to fill the hole. Moving air is wind. at night the opposite happens.

Answer 3

It is windy because it is just moving air!

Answer 4

because it is backwind
