Humewood Pier - surf spot statistics

Best Surf Season (December - March)

Summer in the Southern Hemisphere brings the highest percentage of offshore wind conditions at Humewood Pier, with ideal S-SSW breezes blowing clean across the NNE-facing beach nearly 28% of the time. While the average swell heights dip to a modest 1.9-2.0m, the long-period groundswells from the South and Southwest (10-11s) combine with light offshores to produce clean, rippable waves. Don't expect any direct N-NE swell – that's virtually absent – but the combination of glassy mornings and punchy 1-1.5m sets from the dominant SSW can still deliver fun, groomed peaks, especially when a passing cold front aligns the wind perfectly.

Fair Surf Season (April - May & September - November)

During the shoulder months, the balance shifts. Swell energy slowly ramps up in autumn (April and May) with average heights reaching 2.1-2.2m and periods stretching to 12s, but the frequency of ideal light offshore wind drops to 23-25%. Spring (September to November) sees a similar mix: average swell around 2.1-2.3m with 11-12s periods, and favorable wind only about 22-25% of the time. The dominant swell direction remains stubbornly from the SSW-SW, meaning the pier rarely sees optimal N-NE swell. However, on those days when a high-pressure system stalls offshore and delivers a steady south-westerly breeze, the mid-sized swell becomes clean, powerful, and eminently surfable.

Low Surf Season (June - August)

Winter is the most challenging period at Humewood Pier. The average wave heights increase to a solid 2.3-2.4m with long periods of 12.2-12.5s, indicating plenty of deep-ocean energy. Unfortunately, that's when the prevailing wind most often turns against the spot. The percentage of ideal S-SSW offshore wind plummets to 18-21%, while the onshore N-NE winds become more frequent and gusty, ruining wave quality. The swell direction remains locked in the SSW-SW quadrant, so even the bigger groundswells are often accompanied by cross or onshore winds, creating choppy, difficult conditions. The few good days come when a rare winter cold front delivers a short window of offshore flow; otherwise, it's a waiting game for the spring transition.

June: Winter Lows Bring Size, but Onshore Winds Prevail

Winter peaks in June with average swell height reaching 2.3m and period 12.4s – the most powerful combo of the year. Unfortunately, the ideal offshore wind frequency drops to its annual low of 18%. Swell now comes heavily from SW (26%) and SSW (22%), with a notable increase in SW energy. The north-northeast quadrant wind becomes a major player: N (6.5%), NNE (5.8%), NE (6.3%), and even NNW (8.9%) – all onshore or cross-onshore for the NNE-facing beach. Onshore winds dominate around 60% of the time. The result is big, messy, and often unrideable surf. However, the rare day with a strong S-SW flow can turn the pier into a heavy, pumping reef-like wave. Those days are few and far between.
