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.

In June, Mangamanu offers decent surf conditions with an average swell height of 1.7m and a strong period of 10.8s, indicating powerful, well-formed waves. The most consistent swells approach from the south, with the highest frequency and size in the 1-2.5m range, particularly from S and SSE directions. These swells make up the majority of the surfable waves, providing reliable options for experienced surfers. Wind conditions are rideable only 33% of the time, with the best scenario being light offshore or cross-offshore winds. Stronger winds predominantly come from the northern and western quadrants, which may create chop or unfavorable onshore conditions. The spot handles larger swells well, but surfers should watch for wind shifts to maximize quality sessions. Overall, June delivers solid waves, though wind reliability is the limiting factor.
