Wilderness - surf spot statistics

Wilderness, South Africa, offers consistent surf year-round, but the best conditions typically occur between April and August. During these months, ground swell dominates (62-72% probability), providing cleaner, more organized waves compared to wind swell, which is less favorable. Mean swell size is also most reliable in this period, averaging 2.2-2.4m, with June and July seeing the largest waves (2.3-2.4m). Wind conditions improve significantly from May to July, with good winds occurring 27-31% of the time—still not ideal, but better than other months when bad winds dominate (69-86% probability). The worst months for surfing are January, February, October, November, and December due to higher wind swell influence (53-62%) and poor wind conditions (81-86% bad winds). Swell size drops slightly in these periods (2.0-2.2m) with less ground swell contribution. March and September offer transitional conditions, with March slightly better due to higher ground swell likelihood (56%) and marginally improved winds. Overall, mid-autumn to mid-winter (April-August) is prime for experienced surfers seeking quality waves, despite still challenging wind patterns. For those prioritizing cleaner conditions, June and July stand out, though patience with wind is required.

December at Wilderness offers solid surf conditions with an average swell height of 2.0m and a decent period of 9.9s, providing powerful and well-formed waves. The swell distribution favors SSW, SW, and S directions, with the majority of waves in the 1.5–2.5m range, ensuring consistent rideable energy. However, wind conditions are hit-or-miss—only 15% of the time is it ideal (light offshore/light cross-shore), with the predominant winds coming from NNE to NE and SSW to SW, often blowing at 10–30kph. This means frequent onshore or cross-onshore winds, which can create choppy or less clean faces. When the wind aligns, expect clean, powerful waves, but be prepared for variable surface conditions due to the wind volatility. Advanced surfers will find good opportunities, especially when shorter-period swells mix with the dominant groundswells for punchy sections.
