Stent Road - surf spot statistics

Stent Road in New Zealand is a consistent surf spot with year-round swell, primarily driven by ground swells, which dominate between 67-79% of the time. Wind swells contribute the rest, but there is rarely a flat day (0% no swell). The mean swell size increases from summer to winter, peaking at 2.5m from June to October, making these months ideal for larger waves. However, wind conditions are challenging, with bad winds (onshore or cross-shore) occurring 82-89% of the time year-round. The best balance of swell size and slightly improved wind conditions occurs in autumn (April-May) and late winter (August), where ground swells remain strong (76-79%) and mean swell hovers around 2.1-2.5m, though winds are still unfavorable 83-85% of the time. Summer (January-March) offers smaller swells (1.8-1.9m) and marginally better winds (13-18% good conditions), but the waves are less powerful. Overall, Stent Road is most rewarding for experienced surfers willing to tolerate tricky winds, with the biggest and cleanest opportunities likely in late autumn and early winter (May-July). For smaller but slightly more manageable conditions, February and March provide a modest window before winds deteriorate further into spring and summer.

November at Stent Road delivers consistent surf conditions with an average swell height of 2.2m and a solid period of 11.7s, indicating powerful, well-formed waves. The dominant swell directions are WSW and SW, contributing to the majority of rideable waves, with WSW swells producing the highest frequency of larger waves (1.5m+). Conditions are best when swells come from these directions, offering clean, powerful walls, though SW swells also provide good opportunities, especially in the 1.5-2.5m range. Wind conditions are less favorable, with only 11% of days offering ideal offshore winds, primarily from the ENE to ESE. Most winds are onshore (W to NW) or sideshore (SW to S), which can create choppy or tricky conditions, particularly when stronger (20-40kph). Surfers should watch for windows of lighter ENE/ESE winds or early mornings when winds are calmer. Overall, expect punchy, powerful waves with some wind challenges, but when the elements align, the spot can fire with quality rides.
