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.

December at Humewood Pier offers consistent surf with an average swell height of 2.1m and a solid period of 11.0s, providing well-organized, powerful waves. The dominant swell direction is from the SSW, contributing the highest percentage of rideable waves, particularly in the 1.5-2.5m range (peaking at 24% for 1.5-2m SSW). This direction typically shapes clean, surfable waves thanks to the pier’s orientation. Winds are a mixed bag—while 25% of the time they’re ideal (light to moderate offshore or cross-offshore), ENE and E winds (often 20-40kph) can create chop, especially on bigger days. SSW swells combined with lighter SSE or SE winds tend to deliver the best conditions, offering clean faces with minimal onshore interference. Expect bigger sets (2m+) to appear regularly, but be mindful of wind shifts. Advanced surfers will find December a reliable month with strong, punchy waves, though patience may be needed for optimal wind windows.
