Mangamanu - surf spot statistics

Mangamanu in New Zealand offers surfable conditions year-round, with seasonal variations in swell quality and wind patterns. The best months for surfing are typically from March to August, when ground swells dominate (51% to 59%) and mean swell sizes range from 1.5m to 1.7m. During this period, ground swell consistency peaks, particularly in May (59%) with June and July delivering the largest waves (1.7m). Wind conditions improve slightly in the autumn and winter months (May to July), with good wind days averaging 34%, still outnumbered by poor winds but less severe than summer. The summer months (December to February) see a higher proportion of wind swells (58% to 69%) and smaller waves (1.2m to 1.4m), paired with the worst wind conditions (72% to 73% unfavorable). September marks a transition, with ground swells dropping below 50% but still offering decent wave heights (1.5m). While surfable, the shoulder seasons (September to November and late summer) present more mixed conditions, with weaker ground swells and persistent onshore winds. For the most consistent and powerful waves, target the mid-autumn to mid-winter window when ground swells are strongest and winds are marginally less disruptive.

May at Mangamanu offers decent surf conditions with an average swell height of 1.6m and a solid period of 10.9s, promising consistent, well-formed waves. The dominant swell directions are from the south (S, SSE, SSW), contributing to the majority of rideable waves, with a notable percentage in the 1-2.5m range. This suggests a mix of intermediate to larger waves, suitable for experienced surfers. Easterly swells (E, ESE, ENE) also play a role, adding variety when they align with the break. Wind conditions are favorable 34% of the time, with lighter winds from the east and southeast being ideal. However, stronger winds from the north and west can create choppy conditions, particularly when blowing onshore. Overall, May delivers reliable surf, especially on south swells with offshore or light easterly winds, but watch for windy days that may disrupt quality. For advanced surfers, there are solid opportunities when the swell and wind align.
