About this spot

About

Clarence River is an exposed point/rivermouth surf break north of Kaikoura, producing consistent waves in winter. It’s known for hollow right-handers and barrels when the river’s sand and shingle banks are properly formed and aligned with the swell. The spot depends on the state of the river mouth: strong river outflow and shifting banks can make the wave pattern vary, especially after floods. Following significant rainfall, logs and other debris may be present, and the dredged banks can change quickly, so conditions can be different from one session to the next. Best results are reported with a southeast swell and offshore winds from the southwest, with June highlighted as the strongest month. Summer is often mostly flat compared with winter, and offshore conditions matter for keeping the surf clean. Surfing here is generally not a beginner-friendly environment. Expect strong currents/rips typical of river mouths, moderate shore break, and heavy paddling on larger sets, along with a lack of on-site rescue services or lifeguards. Plan for cold-water sessions, bring appropriate safety gear, and check for debris after heavy rain before going out.

  • Consistent winter surf with hollow/barreling potential
  • Works best with southeast swell and southwest offshore winds
  • River-mouth conditions can change after floods
  • Rarely crowded due to remote location
