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.

May at Humewood Pier offers consistent surf with an average swell height of 2.3m and a strong 12.2s period, providing powerful, well-formed waves. The dominant swell directions are from the south to southwest (SSW being the most frequent at 46.97% for waves over 1.5m), creating long, clean lines ideal for intermediate to advanced surfers. Wave quality is generally good, with the highest frequency of rideable conditions occurring in the 1.5-2.5m range (SSW accounts for 37.83% in this bracket). However, wind conditions are less favorable—only 20% of the time is the wind ideal (light offshore or sideshore). Winds are predominantly from the west and northwest (strongest in WSW and W directions), often blowing 20-40kph, which can cause chop and reduce wave quality. While the swell is reliable, surfers will need to time sessions around wind shifts to score cleaner conditions. Overall, May delivers solid waves but requires patience for optimal sessions.
