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 March offers surfable conditions with an average swell height of 2.0m and a solid period of 11.6s, providing consistent energy for quality waves. The swell direction is predominantly from the SW (26.23% of waves over 1.5m), which aligns well with the beach's orientation, generating clean, rideable surf. ENE and E swells also contribute (7.1% combined over 1.5m), adding variety but with less frequency. Wind conditions are less favorable, with only 17% ideal for surfing, as northerly and westerly winds (NNE, SW, WSW) dominate, often bringing onshore or cross-shore breezes at 10-30kph. Stronger winds (20-50kph) occur ~30% of the time, mainly from NNE, SW, and WSW, which can chop up conditions. The best windows are during lighter SSE-E winds (under 20kph), but these are rare (~3.5% total). Expect peaky, powerful waves on SW swells when winds cooperate, but be prepared for frequent wind-affected sessions. Size-wise, 1.5-2.5m waves are most common (28.34%), offering overhead to double overhead rides, while bigger sets (over 2.5m) occur 1.41% of the time—suited for experienced surfers. Overall, March delivers solid SW groundswells but requires patience for cleaner conditions.
