The Island - surf spot statistics

The Island in New Zealand offers surfable waves year-round, with the best conditions typically spanning from March to August. During these months, ground swell dominates, peaking in May (59%), ensuring cleaner, more organized waves. The mean swell size also increases, reaching its highest point in June and July at 2.4m, providing powerful, consistent surf. Wind conditions remain challenging year-round, with bad winds prevailing over 75% of the time. However, the slightly better wind windows in February, May, and September (23% good winds) offer brief respites. Early autumn (March-May) is particularly favorable, balancing decent swell size (2.0-2.2m) and ground swell prevalence. Winter (June-August) delivers the biggest waves but comes with harsher winds. Late spring and summer (November-January) see weaker swells (1.7-1.8m) and higher wind swell influence, making sessions less predictable. Advanced surfers will find the strongest conditions in mid-winter, while those prioritizing slightly cleaner winds may prefer late summer or early autumn.
