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.

February at Aramoana offers decent surf conditions with an average swell height of 1.9m and a solid 11.0s period, ensuring quality waves with good energy. The swell predominantly comes from the SW, SSW, and S directions, producing rideable waves (1–2.5m) over 60% of the time, with SW swells delivering the most consistent size (10.91% in the 1–1.5m range and 9.49% in the 1.5–2m range). However, wind conditions are tricky—only 18% of the time are they ideal for surfing, with NNE and SW winds often blowing at 10–30kph, which can create chop or cross-shore interference. SW winds (the dominant direction) are particularly problematic, frequently reaching 20–40kph, making sessions challenging unless early mornings or protected spots are timed right. For advanced surfers, February can deliver powerful, clean peaks when wind and swell align, but patience (or dawn patrols) is key to scoring the best sessions.
