Wilderness seasonal overview
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.
