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.

August at Blaketown Wedge delivers consistent and surfable conditions, with an average swell height of 2.0m and a solid period of 12.7s, ensuring powerful, well-organized waves. The primary swell direction is from the WSW, contributing the majority of rideable waves—particularly in the 1-2.5m range (45.42% combined). Larger swells (over 2.5m) are rare but occur occasionally (1.73% total), offering potential for advanced surfers. Cross-shore or offshore winds (ideal for surfing) prevail 50% of the time, with lighter easterly and northeasterly winds (0-20kph) being most common. However, stronger onshore winds (WNW to SW) can occasionally disrupt conditions, particularly at higher speeds (20-40kph, ~8.5% occurrence). Overall, August provides reliable, mid-sized waves with decent shape, though wind variability may require selective timing for optimal sessions. Experienced surfers will find the most opportunities, especially when WSW swells align with lighter winds.
