Aramoana - surf spot statistics

Aramoana, New Zealand, is a surf spot with consistent swell year-round, offering primarily ground swells with a mix of wind swells and almost no days without waves. The best months for surfing here are from March to August, when ground swell dominance is highest (70-75%), swell sizes are larger (mean 2.0-2.3m), and conditions are most favorable for surfers seeking powerful, clean waves. However, wind conditions are generally challenging throughout the year, with only 15-18% of days having good offshore or cross-shore winds—most days (82-85%) experience onshore or unfavorable winds. The worst months are December and January, when ground swells drop below 60%, wind swells increase, and wave size decreases slightly (1.8-1.9m). While winter months (May-August) provide the biggest and most consistent ground swells, surfers should be prepared for strong onshore winds and colder water. Late summer and early autumn (February-April) can be a reasonable compromise, offering slightly better wind odds while still maintaining decent swell size and quality. Advanced surfers will find the most opportunities in this window, but patience is required to score the rare days with clean conditions.

July at Aramoana delivers solid surf conditions with an average swell height of 2.2m and a strong period of 11.6s, ensuring well-formed and powerful waves. The dominant swell direction comes from the SSW to SW, accounting for the highest frequency of rideable waves, particularly in the 1.5-2.5m range. This setup favors consistent, clean waves with good energy, though larger days (over 2.5m) are less frequent but present. Wind conditions are more variable, with only 15% of days offering ideal offshore or light cross-shore winds—typically from the NE to E quadrant. However, stronger onshore winds from the W to NW are common, which can degrade wave quality. Surfers should target days when winds align from the ENE to ESE for cleaner conditions. Overall, July provides reliable surf, but patience is needed to score the best sessions when wind and swell align.
