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.

October at Mangamanu delivers a solid mix of surfable conditions, though consistency and ideal winds can vary. The average swell height is 1.4m with a decent 10s period, providing enough energy for quality waves, particularly when swells align with the spot’s orientation. The most dominant swell directions come from the S to SSE, accounting for the majority of waves in the 1-2.5m range, offering punchy, well-formed sets. Smaller but still surfable swells occasionally arrive from the E-ENE, but they lack the same power and consistency. Wind conditions are favorable only 30% of the time, with lighter winds from the E to SE being ideal. However, stronger winds frequently blow from the N to NW, creating choppy or blown-out conditions, especially when combined with larger swells. Surfers should monitor forecasts for S/SSE swells paired with light easterly winds—these windows provide the cleanest and most rideable waves in October. Overall, it’s a month with potential, but patience and timing are key to scoring good sessions.
