Shipwreck Bay - surf spot statistics

Shipwreck Bay in New Zealand is a consistent year-round surf spot, predominantly powered by ground swells, which dominate the swell mix nearly every month with percentages rarely dropping below 84%. The swell size averages around 1.5m to 2.2m, peaking in July and August at 2.2m, making these months ideal for surfers seeking larger waves. However, the biggest challenge here is wind conditions, which are frequently unfavorable, particularly from February through December, with bad wind conditions occurring over 60% of the time. The best wind conditions, though still relatively low, are found in January (38% good winds), making it the most promising month for clean surf. December has the highest proportion of wind swell (16%), which can create less ideal, choppier waves. If you prioritize wave consistency, the winter months (June-August) offer the biggest swells, but expect strong offshore winds to be rare. For more manageable conditions, late summer (January-March) provides slightly better wind odds while still maintaining solid swell activity. Ultimately, Shipwreck Bay delivers waves year-round, but surfers must contend with challenging winds outside of the January window.

April at Shipwreck Bay offers solid surf conditions with an average swell height of 2.0m and a strong period of 13.8s, indicating powerful, well-spaced waves. The dominant swell direction is from the SW (36-49% of swells between 1.5-2.5m), producing consistent, quality waves with good shape and energy. ENE and ESE swells also contribute occasionally but tend to be smaller. Wind conditions are favorable 25% of the time, with lighter winds from the NE to E sectors (0-20kph) providing cleaner surfaces. However, stronger winds from the S to SW (20-40kph) are more frequent, potentially creating choppy conditions. Mid-sized waves (1.5-2.5m) dominate, making it ideal for experienced surfers, while smaller days (0.5-1.5m) are less common but manageable for intermediate riders. Overall, expect powerful, SW-driven swells with variable wind conditions—best sessions occur when offshore NE/E winds align with the SW swell.
