About this spot

About

Kakanui River Mouth is an exposed beach/river bar surfing spot on the Kākaunui Coast, producing both left and right waves depending on how the sandbar is formed. It’s generally considered a reliable, year-round option when conditions line up, with surf possible at all stages of the tide. For the cleanest, most favorable sessions, the setup is typically South to Southeast (with East also noted) swell paired with offshore West to Northwest winds. Under these conditions the bar can form well and the waves can peel for substantial distances off the bar. While conditions are often described as consistent, you should plan for a mix of hazards typical of river-mouth breaks. Strong river outflow and tidal rips are especially likely after heavy rain or during larger swells, and river debris or shifting sandbars can change the exact takeoff/paddle route. Safety is a top priority here: shark sightings have been reported. Avoid surfing alone and consider avoiding low-light periods such as dawn/dusk. There are no lifeguards on-site; the nearest hospital is in Oamaru (about 15 minutes away).

  • Works year-round; best reported swell/wind alignment involves South to Southeast swell with offshore West or Northwest winds
