Surfing is a surface water sports in which the wave rider, referred to as a surfer, rides on the forward or deep face of a moving wave, which is usually carrying the surfer towards the shore. Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or in rivers in the form of astanding wave or tidal bore. However, surfers can also utilize man-made waves such as those from boat wakes and the waves created in artificial wave pools.
