Long Reef Beach extends for 1.8 km from the base of Long Reef Point to Dee Why Point and is backed by 25 ha Dee Why Lagoon. The beach faces the southeast and picks up any east to southeast swell making it one of Sydney's higher energy beaches. The waves average 1.6 m being highest in the south and centre, decreasing north of the Long Reef surf club owing to waves breaking on the outer reefs. Between Long Reef surf club and Dee Why Point are usually eight strong rips, including the particularly hazardous rip that flows out against Dee Why Point. The rips and their feeder currents usually form a continuous trough with currents heading into the rips.
