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.

May at Blaketown Wedge offers solid surf conditions, with an average swell height of 2.0m and a consistent swell period of 12.4s, indicating powerful, well-spaced waves. The dominant swell direction is WSW, contributing most of the rideable waves (particularly in the 1-2.5m range), while WNW and NNW swells also provide occasional mid-range surf. Wind conditions are favorable for surfing 48% of the time, with lighter easterly winds (E, ESE, ENE) being the most common, though stronger SW and WSW winds can occasionally create choppy conditions. The spot works best in offshore or light cross-shore winds from the east to northeast, which help clean up the powerful swells. Expect a mix of mid-sized and larger days, with the best sessions likely when WSW swells coincide with lighter easterly winds.
