10-day surf forecast with Strike Scores for Mandurah Wedge, Mandurah, Australia
Mandurah Wedge is a punchy breakwater setup south of Perth where refracted Indian Ocean swell folds into a steep right-hand wedge. It is best known as a bodyboarding wave: short, fast, and capable of throwing vertical ramps when the bank and backwash line up. The rock wall makes conditions unpredictable, so it suits experienced riders who can read moving water and avoid the structure.
