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 February, Mangamanu offers decent surf conditions with an average swell height of 1.4m and a solid period of 10.0s, providing good energy for riding. The swell is predominantly from the S, SSE, and SE directions, with a strong frequency in the 1-1.5m and 1.5-2m ranges, ensuring consistent, rideable waves. Swells from the E and ENE also contribute, adding variety to the mix. Wind conditions are less favorable, with only 27% of the time being ideal for surfing. The wind is often from the N to NE quadrant at moderate speeds (10-30kph), which can create chop, especially with stronger NNE or NE winds. However, lighter ESE to SE winds (0-20kph) occasionally provide cleaner conditions. The spot handles larger swells well, with occasional bigger sets (2-2.5m) from the S and SSE, offering punchier waves for experienced surfers. Overall, February delivers a mix of workable conditions—best when winds cooperate, with the most consistency in mid-sized swells from southerly directions.
