Blaketown Wedge - surf spot statistics

Blaketown Wedge in New Zealand is a powerful and challenging surf spot that thrives on consistent ground swell and favorable wind conditions. The best months for surfing here are typically from May to August, when the swell is most reliable, and wind conditions are more favorable. During this period, ground swell dominates (74-77%), with mean swell sizes ranging from 1.9m to 2.1m, providing powerful waves ideal for experienced surfers. The likelihood of good wind conditions peaks in June and July at 52-54%, reducing the chance of onshore winds that can ruin the surf. Outside these months, conditions become less favorable, particularly from November to February, when ground swell decreases (63-71%), wind conditions worsen (32-39% good winds), and swell size drops to around 1.5m-1.7m. September and October still offer solid swell heights (2.1m) but come with increasing bad wind probabilities (59-64%), making sessions more inconsistent. Overall, winter (May-August) delivers the most consistent and high-quality surf at Blaketown Wedge, while summer months tend to be less reliable due to weaker swells and more frequent onshore winds.

December at Blaketown Wedge offers consistent surf conditions with an average swell height of 1.7m and a solid 11.3s period, indicating powerful, well-spaced waves. The swell direction is predominantly from the WSW and W, contributing to 66% of waves in the 1-2.5m range, with the largest concentration (22%) in the 1-1.5m range from WSW. This suggests a reliable mix of mid-sized to larger waves, though bigger sets (over 2.5m) are rare. Wind conditions are less favorable, with only 32% of days offering ideal offshore or light cross-shore winds (mostly from E-ENE at 0-20kph). However, stronger onshore winds from W-WSW (10-30kph) occur frequently, potentially creating choppy conditions. Advanced surfers will find the most opportunities when winds align, as the swell energy and direction provide powerful, steep walls when clean. Expect smaller, more manageable waves from NW-NNW directions, though they’re less common. Patience is key—wait for those lighter wind windows to score the best sessions.
