As more and more of the wave front encounters shallower water and slows down, the wave font refracts and the waves tend to align themselves nearly parallel to the shoreline (they are refracted towards the region of slower speed). Sea waves are mostly formed by winds moving across the surface of the sea water, pushing the surface water along until it forms waves of energy.
