Stent Road - surf spot statistics

Best Surf Season (March - August)

The heart of the winter swell window arrives in March and persists through August, delivering consistent, powerful groundswells from the W/SW quadrant. Average wave heights hold steady between 1.7 and 2.1 m with periods averaging well over 11 seconds. The SE trade wind influence remains strong during these months, providing ample offshore opportunities. This is the prime time to score Stent Road at its best – lined-up, long-period swell with clean, offshore conditions.

Fair Surf Season (February & September)

February offers the highest percentage of offshore wind (22%) but with slightly smaller average swell heights (1.5 m). September, conversely, still sees substantial swell (2.1 m) but the wind reliability drops off significantly. Both months require careful timing to catch the right combination of size and shape.

Low Surf Season (October - January)

The spring and early summer months see a dramatic decline in consistent surf quality. While October maintains overhead swell, the wind patterns become dominated by westerly quadrants, making clean conditions scarce. November through January see both swell size and period drop, with offshore wind windows becoming less frequent. Surfable days are rarer, but occasional clean, smaller days can occur under high-pressure setups.

March: Autumn Kick-Off with Stronger Swell

March marks the transition to autumn, with average swell height climbing to 1.7 m and period stretching to 12.1 s. The WSW still accounts for 45.1% of all swells, but SW surges to 13.5%, injecting more power. Wind patterns remain favorable – the offshore component from SE (13.0%) and SSE (8.4%) keeps the ideal wind percentage at 21%. This combination yields punchy, long-period waves in the 1.5-2 m range. When a high-pressure system sits east of New Zealand, Stent Road lights up with consistent, clean sets.
