Surge channels can form in reefs,[2]: 14 [5] and the term is sometimes also applied to breaches of coastal dunes by storms.[6][7]

Surge channels can range from a few inches across to ten feet or more across. They may create

tide pools if the conditions are suitable, but the rapid water movement typically creates a dangerous situation for people or animals that are caught by the current.[8] The West Coast Trail on the coast of Vancouver Island is known for its large number of surge channels, some of which are impassable even at low tide and must be crossed inland.[9][10]
