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.

In August, Aramoana delivers consistent surf with an average swell height of 2.2m and a solid period of 11.7s, indicating powerful, well-spaced waves. The dominant swell directions are SW, SSW, and ENE, with SW swells (6.13% in the 1-1.5m range and 8.32% in the 1.5-2m range) providing the most frequent and sizable waves. Larger swells (2m+) are common, particularly from ENE, E, and S directions, offering overhead conditions for experienced surfers. However, wind conditions are variable—only 17% of the time is offshore (E to SE), creating clean faces. Predominantly, winds blow from the N to W quadrant, often at 10-30kph, leading to choppy or cross-shore conditions. While SW winds can be strong (1.72% over 40kph), they’re manageable given the spot’s exposure. Overall, August is a reliable month for intermediate to advanced surfers, with good size and energy, though wind quality is inconsistent. Patience pays off when the rare offshore days align with the swell.
