Taronui Bay - surf spot statistics

Taronui Bay in New Zealand offers surfable waves year-round, but the best conditions for surfers typically occur during the autumn and early winter months, particularly from March to June. During this period, ground swell frequency increases slightly compared to other seasons, ranging from 25-29%, while wind swell remains dominant at around 64-68%. The mean swell size holds steady at 1.2-1.3m, providing decent wave energy without being overly massive. Wind conditions are less favorable overall, but March stands out with 33% good wind days, the highest probability of offshore or light winds all year. From May onward, wind quality deteriorates further, with bad wind conditions exceeding 70%. Summer months like January and February see higher wind swell dominance (68-76%) and smaller ground swell contributions, combined with poor wind reliability (only 30-33% favorable). Swell size remains modest at 1.2-1.3m. Winter (July-September) brings similarly mixed conditions, with ground swell persisting around 22-27%, but wind conditions worsen significantly, dropping to just 19-20% favorable. Spring (October-November) is the least consistent, with ground swell dropping to 18-21% and mean swell size decreasing to 1.0-1.1m, alongside persistently poor wind stats. For surfers seeking the best balance of swell size and wind quality, March is the standout month, followed by April and May for slightly smaller but still rideable waves. However, since onshore winds dominate year-round, Taronui Bay likely works best on specific days when wind direction shifts favorably rather than relying on seasonal averages.

In May, Taronui Bay offers surfable conditions with an average swell height of 1.2m and a decent period of 9.3s, providing relatively clean and manageable waves. The swell direction is predominantly from the ENE, E, and NNE, with the highest frequency of waves in the 0.5–1.5m range, making it suitable for intermediate surfers. Larger swells (1.5–2.5m) occur less frequently but can bring more powerful waves for advanced riders. Cross-shore or offshore winds, which are ideal for surfing, occur 24% of the time, mainly from the NW to NE sectors. However, onshore winds from the S to WSW directions are more common and can create choppy conditions. The wind speeds are often moderate (10-30kph), but stronger gusts (30-50kph) occasionally disrupt wave quality. Overall, May delivers a mix of smaller, clean sessions and occasional solid swells, with the best windows depending on wind alignment.
