Shore Break Art By Clark Little

A reef break happens when a wave breaks over a coral reef or a rocky seabed. These waves are perhaps the most dangerous if a surfer wipes out badly. Example are Cloudbreak in Fiji and Jaws in Maui.
Shore break
A shore break is a wave that breaks directly on, or very close to the shore. This happens when the beach is very steep at the shoreline. Oahu in Hawaii is known to have some the largest shore breaks in the world, measuring up to a height at least a meter.
