Yanchep Lagoon is one of Perth’s most famous coastal treasures. A shallow, crystal-clear body of water is formed by a primary limestone reef that runs parallel to the shore for about 200 meters. The southern end hooks into the beach, creating a highly protected basin that is perfect for children, beginners, and macro snorkelers.

What is the visibility at Yanchep Lagoon?
Typical visibility at Yanchep Lagoon is around 5m, best on calm days after a settled dry spell. VisPro Dive publishes a live visibility forecast for Yanchep Lagoon each day. VisPro Dive gives every site a daily Divability Score out of 100 and a visibility estimate.
When is the best time to dive Yanchep Lagoon?
The best time to dive Yanchep Lagoon is during calm weather with light winds and low swell — best visited during light Easterly, South-Easterly, or North-Easterly winds (ideally 5–10 knots) to ensure glassy, flat surface conditions. High tide is highly recommended if you plan to explore the back of the reef, as low tide causes waves to churn up sediment and drop visibility inside the basin.
