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.

January at Humewood Pier delivers solid surf conditions with an average swell height of 2.1m and a decent period of 11.0s, ensuring well-formed waves. The dominant swell direction is from the SSW, accounting for nearly 50% of waves between 1.5m and 2.5m, offering powerful, clean walls ideal for experienced surfers. Smaller but surfable swells from the S, SE, and ESE contribute to variety, though they’re less consistent. Wind is a mixed bag—only 25% of the time is it ideal (light offshore or cross-offshore), primarily from the W to NW. However, ENE to ESE winds (20-30% occurrence) often bring onshore chop, particularly at higher speeds (20-40kph), which can degrade wave quality. Expect some blown-out sessions, but when winds align, the SSW swell produces high-quality rides. A good month for advanced surfers who can time sessions around wind shifts.
