4th groyne

4th Groyne is a surf spot on the Perth southern coastline in Western Australia, part of the stretch of beachbreaks around Perth South. It’s a groyne-assisted beach break, so the sandbanks are influenced by the rock structure, which can help shape more organized waves than the open beach nearby.

What it’s like

• Wave type: Mostly beachbreak, sometimes with better-defined peaks due to the groyne
• Best conditions: Typically does best with a clean offshore breeze and a solid west to southwest swell
• Wave quality: Can be fun and punchy when the sandbanks line up, but conditions can change a lot with shifting sand
• Crowd: Usually local-dependent and can get busy when it’s working
• Vibe: A practical, straightforward surf zone rather than a highly protected or famous reef setup

What to expect

• Can be inconsistent because it relies on sand movement
• Best for: Surfers comfortable reading beachbreaks and adapting to changing peaks
• Hazards: Groyne rocks, shifting banks, and strong currents after bigger swells

In short

4th Groyne is a malleable Perth South beachbreak that can offer fun, rippable waves when the sand and swell line up, but it’s not always a guaranteed, high-performance spot.
