Yanchep Lagoon - Southern Lagoon Beach

Moderate risk: Rip currents over reef

A powerful rip current forms when incoming tide cascades over the reef, flowing away from shore through the surf zone. Year-round risk but strongest in summer when most visitors are present.

Moderate risk: Deep drop-off zones

Deep drop-offs to 3 m inside the lagoon and up to 7 m outside the reef; less confident swimmers should stay between the flags.

Moderate risk: Deep water beyond reef

Outside the reef, depths drop to 7m with stronger currents beyond the patrolled area.

Low risk: Shifting sand bars

Shifting sand bars can temporarily swallow protected swimming sections; check conditions on Beachsafe before visiting.

Low risk: Shark presence

Sharks are present in WA waters; occasional sightings may close the beach.

Low risk: Reduced visibility at low tide

At low tide, waves crash against the back of the reef churning up sediment and reducing visibility.

Low risk: Shifting sand bar at southern end

Shifting sand can temporarily close off the protected southern lagoon section throughout the year.

Low risk: Low tide turbidity

Low tide creates waves crashing against the back of the reef, churning up sediment and reducing visibility.
