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.

January at Wilderness offers decent surf conditions with an average swell height of 2.0m and an ideal 10-second period, providing good energy for intermediate to advanced surfers. The most consistent swells come from the south-southwest (SSW), making up over 27% of waves in the 1.5m+ range, with strong contributions from the east-northeast (ENE) and east (E) directions as well. The majority of waves fall between 1.5-2.5m, ensuring rideable surf most days. However, wind conditions can be tricky—only 15% of the time is the wind ideal (light offshore or sideshore). The predominant winds are from the northeast (NE) to east-northeast (ENE), often blowing 20-40kph, which can create choppy or cross-shore conditions. Stronger NNE/NE winds occasionally bring higher speeds, potentially ruining the wave face. When the wind shifts to lighter southerly or easterly directions, it improves conditions significantly. Overall, January delivers consistent, mid-sized waves, but patience is key for clean sessions given the frequent onshore winds.
