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.

June at Humewood Pier delivers consistent surf with an average swell height of 2.5m and a solid 12.4s period, indicating powerful, well-formed waves. The dominant swell direction is SSW, contributing the highest percentage of larger waves (1.5m and above), making it the primary source of rideable conditions. SE to SW swells also provide decent opportunities, though with less consistency. Wind conditions are less favorable overall—only 16% of the time are they ideal for surfing—with problematic W to NW winds being the most frequent, often blowing at 20-50kph, which can create choppy or cross-shore conditions. However, when winds are light or offshore (E to SE), the spot can offer clean, well-shaped waves, particularly during larger SSW swells. Expect a mix of powerful, mid-sized days and occasional bigger, more challenging sessions, best suited for experienced surfers who can handle the variable winds and stronger swell energy.
