Humewood Pier - surf spot statistics

Humewood Pier in South Africa is a consistent year-round surf spot with reliable ground swells dominating the conditions. The best months for surfers are generally from May to September when ground swell percentages peak (85-89%), ensuring cleaner, more powerful waves with mean swell sizes ranging from 2.3m to 2.5m. These months also offer the largest waves, particularly June and July, where the swell size averages 2.5m—ideal for intermediate to advanced surfers. However, wind conditions are less favorable during this period, with bad wind conditions (onshore or cross-shore winds) occurring 80-84% of the time, which can create choppy surf. The earlier months like May and September strike a decent balance between swell size and slightly better wind odds. From October to April, ground swells decrease (61-77%), but wind conditions remain poor (75-80% bad winds), though the swell size is still respectable (2.1-2.3m). January to March sees higher wind swell influence, potentially reducing wave quality. Overall, the best compromise between swell size and wind conditions is likely late autumn (May) or early spring (September), when ground swells are strong but wind interference is slightly less severe compared to mid-winter. Advanced surfers may prioritize June and July for bigger waves despite the wind, while those seeking slightly cleaner conditions might prefer the shoulder months.

In August, Humewood Pier experiences solid surf conditions with an average swell height of 2.5m and a strong 12.2s period, indicating powerful, well-spaced waves ideal for experienced surfers. The dominant swell direction is from the SSW, contributing to the largest portion of waves, particularly in the 1.5–2.5m+ range, ensuring consistent, high-quality surf. However, the wind is only favorable 19% of the time, with the most problematic winds coming from the WSW to W, which are often strong (20–50+ kph) and can create choppy or onshore conditions. Cleaner sessions are more likely when winds are lighter and from the E to SE, though these scenarios are less frequent. Surfers should anticipate sizable, powerful waves but be prepared for variable wind conditions, making timing and patience key for scoring optimal sessions this month.
