Wainui Beach - surf spot statistics

Wainui Beach in New Zealand offers consistent surf conditions year-round, with some months standing out as particularly favorable for surfers. The best time to surf here is generally from March to August, when ground swell dominates, wave heights are more substantial, and wind conditions, while still often challenging, show slight improvements compared to the rest of the year. March marks the beginning of the better swell season, with ground swell contributing 51% of the waves and an average swell size of 2.0 meters. This trend continues into April, May, and June, with ground swell peaking at 59% in May, accompanied by the year's highest mean swell size of 2.4 meters in June and July. Wind conditions remain predominantly unfavorable throughout the year, with good wind days hovering around 19-24%, but the slightly higher percentages in autumn and winter (April to August) provide marginally better opportunities. The worst months for surfing are typically November through February, when wind swell dominates (60-66%), ground swell drops significantly (33-42%), and wind conditions are at their poorest (only 19% good wind days). Despite these challenges, Wainui Beach rarely experiences flat spells, with virtually no days without swell. For surfers seeking quality waves, the autumn and winter months (March to August) are the prime window, offering larger, cleaner swells and slightly more manageable winds compared to the summer period.

February at Wainui Beach offers consistent surf with an average swell height of 1.8m and a solid period of 10.2s, providing good energy for intermediate to advanced surfers. The dominant swell directions are E to SE, with the most frequent wave heights falling in the 1-2.5m range, making it reliable for quality rides. ENE and E swells deliver the highest proportion of surfable waves, particularly in the 1.5-2.5m range, which is ideal for performance surfing. Wind conditions are less favorable, with only 19% being ideal (light offshore or sideshore), primarily from W to NW directions. However, moderate onshore winds (10-30kph) from E to S are common, which can create choppy conditions but occasionally groom swells into manageable peaks. Bigger swells (2.5m+) are rare but occur mostly from S to SSW, offering powerful, less crowded sessions for experienced riders. Overall, expect a mix of clean and wind-affected days, with the best surf coming from E/NE swells paired with lighter W/NW winds.
