"The primary generation process of surface waves is the wind (Figure 1.3 below). Differential stresses and pressure along the interface pushes the waves and steepens them."

Out at sea,waves tend to travel in the same direction as the wind is blowing.So, the prevailing winds create the sea waves inside the ocean.Inshore,they often move towards the shoreline irrespective of the wind direction.This is caused by the effects of both diffraction and refraction.
Diffraction causes waves to spread out after they pass through a gap such as a harbour mouth or entrance to an enclosed bay causing the waves to head towards all sides of the harbour.
Refraction occurs when the waves travel into changed conditions ,such as shallow water that is found near a shoreline.

Surface air pressure variation,planet position that changes the gravitational force and lastly due to disturbances due to earthquakes and land slides are all create the sea waves.

Hi,
The reason is due to temperature variation, in the middle of the sea, the air becomes hot. and the air becomes hot. ANd due to wind, the air created in the middle travels towards the wind. which causes the waves.
