In oceanology and geomorphology, the surf cave or surf cave is the hollow at the base of a cliff between the level of the high water and the mean water . A surf cave is created by the erosive effect of the waves and the debris carried along. As marine erosion ( abrasion ) progresses , the rock above breaks off over time and the process of coving begins again. This leads to the gradual shift back of the coast and the formation of an abrasion platform.

Over a longer period of time, the cliff foot can be worn away so far that entire cave systems arise, which are then referred to as surf caves.
