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.

November at The Island delivers solid surf conditions with an average swell height of 1.8m and a decent period of 10.0s, offering well-organized waves. The predominant swell direction is from the south to southeast, with the highest frequency of rideable waves (1.5m+) coming from the SSW (22.56%) and S (10.64%) sectors, ensuring consistent, punchy waves with good shape. ENE and E swells also contribute, but with less frequency. Wind conditions are favorable for surfing 21% of the time, with lighter winds (under 20kph) predominantly from the ENE to ESE, which often align best with the swell direction for clean surf. However, stronger winds from the N to NW can create chop, particularly when combined with larger swells. Overall, expect a mix of good surf days with occasional wind-affected sessions—ideal for intermediate to advanced surfers who can pick the right windows.
