Augusta Rivermouth

Augusta Rivermouth (Margaret River South, WA, Australia) is a scenic river-mouth surf break near the town of Augusta, at the far southern end of the Margaret River region. It’s known for its powerful, often changeable conditions where the river outflow meets the Indian Ocean, creating shifting sandbanks and a wave that can vary a lot from day to day.

What it’s like

• Wave type: Mostly a beach/river-mouth break with sandbar-dependent peaks.
• Consistency: Unreliable and highly tide/swell dependent, but when it lines up it can produce fun, punchy waves.
• Size: Usually works best on moderate swells; bigger swells can make it too powerful or messy.
• Shape: Can offer lefts and rights, but the exact setup changes with sand movement and river flow.

Best conditions

• Wind: Typically prefers light offshore winds or very light variable winds.
• Swell: Southern and southwest swells tend to light it up, especially when there’s enough period for energy to wrap into the mouth.
• Tide: Often better on mid to incoming tides, though the ideal tide shifts with the sand state.
• Season: Can work year-round, but conditions are most commonly surfed when the winter swell trains from the Southern Ocean are active.

Hazards / things to watch

• Strong currents near the river mouth.
• Shifting sandbars and breaking sections.
• Rips and water movement after rain or when the river is flowing.
• Depending on conditions, it can be closeout-prone or uneven.

Overall vibe

Augusta Rivermouth is more of a local, shape-shifting beachie than a dependable marquee pointbreak. When the sand and swell line up, it can be a fun and playful session; when they don’t, it’s often best viewed as a quick-check surf rather than a guaranteed strike mission.
