What is a hole?

A hole is exactly as its name suggests - a deeper area of the shore bed, which can take unsuspecting swimmers by surprise. Besides rip currents, the inshore hole is one of the major problems for swimmers, in particular small children.

How do holes form?

The formation of holes is related to surf conditions and rip currents. However, holes can still be present once both surf and rips have gone. An inshore hole is commonly a trough that runs parallel to the shore, often with considerable variation in depth. Swimmers can be swept into an inshore hole by the backwash of water returning down the face of the beach.
