About
Blaketown Wedge (also known as Wavetraps or Cobden) is an exposed river-mouth surfing spot near Greymouth’s south breakwater. It works as a wedge created by swell reflecting off the southern breakwater/mole, producing fast, hollow right-hand peaks and a performance-focused feel for experienced surfers. Conditions are described as physically demanding and potentially hazardous: strong river mouth currents and dangerous rips are noted, along with a heavy shorebreak and debris (including floating logs) especially after heavy rain. Submerged hazards near the breakwater and shifting sandbar/river-channel variables can also make take-off and holds tricky. The spot tends to perform best when you align key factors: offshore winds from the east (often described as E easterlies) and higher tides. Multiple sources also emphasize that the wave can pick up significant swell and can become extremely heavy or close out on massive swells—while still offering right-hand options inside the river channel during bigger events. Reliability is consistently described as low/unreliable with no clear seasonal pattern. Still, some months (notably late autumn through winter) are singled out for better odds, and crowding is generally described as rarely crowded, with locals tending to control the main peak near the wall.
- Hollow/fast right-hand wedge peaks near the southern breakwater.
- Offshore easterly winds groom the waves.
- Often better on higher tides; can handle larger swell but may close out when extreme.
- Intense, performance-style right-hand wedge peaks near the breakwater.
- Can produce hollow/fast and sometimes barreling sections.
- Rarely crowded, with a small experienced local lineup.
- Unreliable wave conditions and exposure.
- Dangerous rips and strong river-mouth currents.
- Heavy shorebreak and debris after rain.
- Best results tend to require matching offshore east winds and the right tide.

By sport
What to expect for each.
An exposed river-mouth ‘wedge’ that reflects swell off the southern breakwater for intense right-hand peaks; hollow/fast, and can offer right-hand options inside the river channel on bigger swells.
- Wave Direction
- Right
- Optimal Swell
- WSW, W
- Swell Height
- 1–2.5 m
- Optimal Tide
- High, Mid — Higher tides are usually favored; mid-to-high tides are referenced as workable depending on conditions.
- Shelter
- Exposed — Open exposure; semi-protection from the breakwater reflection is noted but the spot remains exposed to the elements.
- Wind Effect
- Best grooming is reported with offshore easterly winds.
- Bigger Swell
- On larger swell it can become extremely heavy and may close out; right-hand options can appear inside the river when swells are big.
- Wave Quality
- Good — Wave quality is described as good, though overall reliability is noted as unreliable/variable.
- Wave Power
- Powerful — Often described as powerful/high-performance.
- Wave Shape
- Hollow — Sources describe hollow/wedgy peaks; one source also describes barreling.
- Peel Speed
- Fast — Peaks are described as fast.
- Ride Length
- Short — Short, intense wedgy peaks are noted; another source gives longer workable walls depending on sandbar alignment.
- Typical Ride Length
- 50–150 m
- Ride Length Details
- Short, wedgy peaks; can become longer/workable depending on sandbar alignment (fast, intense options).
