Motunau Beach Island - surf spot statistics

Motunau Beach Island in New Zealand offers a mix of ground and wind swells throughout the year, with no months entirely devoid of swell. The best conditions for surfing generally occur between April and August, when ground swell dominance increases, averaging 54-58% of the swell mix, resulting in cleaner, more organized waves. During these months, mean swell sizes peak at 1.7-1.9m, providing solid surfable conditions. Wind conditions improve slightly in this period, with good wind days ranging from 28-32%, though onshore winds still dominate. Winter months (June-August) offer the most consistent swell but come with higher wind variability. The summer months (December-February) see a higher proportion of wind swells (61-72%), which can lead to choppier conditions, compounded by less favorable wind patterns (only 20-21% good wind days). For surfers seeking quality waves, the autumn and winter transition (April-July) stands out as the prime window, balancing decent swell size, cleaner ground swells, and marginally better wind odds compared to the rest of the year. However, even in the best months, surfers should expect challenging wind conditions frequently.

In February, Motunau Beach offers decent surfing conditions with an average swell height of 1.6m and a solid period of 9.8s, indicating well-organized, rideable waves. The dominant swell direction is from the northeast and east, with ENE and E swells contributing the most to surfable waves in the 1-2.5m range, providing consistent energy. The wind is favorable for surfing only 21% of the time, often coming from northeast to east, which can create clean conditions when lighter. However, stronger NE winds (20-30kph) are common and may cause choppiness, reducing ideal sessions. SSW and SW winds, though less frequent, can also disrupt conditions. Surfers can expect a mix of small to moderate waves, with the best opportunities arising when swells from the ENE/E combine with lighter winds. Overall, it’s a month with variable but workable surf, requiring patience for optimal sessions.
