This is because when the wind hits the water it moves it kind of creating a ripple effect. Its like the same reason how white caps happen in a big lake.
It is the winds, often far out into the oceans, that create waves.
Winds blowing over a large area create powerful, high, and fast waves.
Earthquake or Strong Winds
Strong winds can create waves larger than normal.
White caps in the ocean are formed when strong winds create waves that break and create foam on the surface of the water.
The size of waves is primarily influenced by the wind speed and the distance (fetch) over which the wind has blown. Stronger winds and longer fetches tend to create larger waves.
Big waves are typically created by strong winds blowing over a large distance of open water, called fetch. The longer the fetch and the stronger the winds, the bigger the waves. Other factors such as storms, tides, and underwater topography can also contribute to the formation of big waves.
The "fetch"http://en.wikipedia.org/wiki/Fetch_%28geography%29
In general, waves tend to be larger and more powerful in the winter due to stronger winds and storms. Additionally, winter storms can create swells that travel long distances and result in bigger waves hitting shorelines.

Sustained winds of 12 to 19 knots are classified as "moderate breezes." In nautical terms, this wind speed can create some waves and is typically associated with pleasant sailing conditions.
