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.

Aramoana in January offers a mix of conditions suitable for experienced surfers, with some variability in swell and wind. The average swell height is 1.8m with a solid period of 10.5s, indicating consistent, well-formed waves. The dominant swell directions are from the southwest (SW) and south-southwest (SSW), contributing the most frequent and sizable waves, particularly in the 1-2.5m range. These swells are most common, with 12.4% of waves from SW in the 1-1.5m range and 6.53% from SSW in the 1.5-2m range. Larger swells (over 2.5m) occur occasionally, mostly from SW at 0.37%. Wind conditions are less reliable, with only 17% of the time offering ideal surfing winds, typically light offshore or cross-offshore. However, winds from the northeast (NE) and east-northeast (ENE) at 10-20kph can provide cleaner conditions, though stronger winds (20-50kph) from the S-SW and WSW directions are more frequent and often create choppier surf. Overall, January delivers decent waves, but surfers should watch for optimal wind windows to maximize quality.
