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.

March at Stent Road offers decent surf conditions with an average swell height of 1.9m and a solid period of 12.2s, indicating well-organized, powerful waves. The primary swell directions are WSW (26.3% of waves between 1-2.5m) and SW (25.2% in the same range), with SSW and SSE also contributing to larger sets (1.5-2.5m). These swells produce consistent, mid-sized waves with occasional bigger days, particularly when WSW or SW swells combine with offshore winds. Wind conditions are less favorable, with only 17% of days providing ideal offshore (E-ENE) or light cross-shore winds. The dominant winds are W-WSW (often 20-40kph), which can create choppy conditions, though mornings may see lighter winds. Expect a mix of surfable days with clean(ish) peaks and others compromised by onshore winds—best suited for experienced surfers who can handle variable conditions and prioritize sessions around wind swings.
