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.

October: Wind Variability Dampens an Otherwise Good Month

October sees average swell height at 2.2m, period 11.0s, and ideal wind at 22%. Swell is still mainly from SSW (21%), SW (15%), and S (11%), but there is a slight increase in E and ENE components (E 4.7%, ESE 8.2%), indicating the summer pattern is not yet fully established. The wind is mixed: ENE (12.6%), E (16.8%), and ESE (7.3%) – all onshore or cross-onshore – combine for about 37% of the time. Meanwhile, offshore quadrants (S through WSW) account for about 22% ideal plus some SW (11%) that can be cross-offshore. The result is a month where swells are strong but wind conditions are highly variable. Pay attention to synoptic charts: when a low pressure passes and the wind goes southwesterly, the pier will light up.
