Kommetjie - surf spot statistics

Kommetjie in South Africa offers consistent surf year-round, with ground swells dominating the swell regime at 75-92% probability, peaking from May to August. The mean swell size ranges from 2.5m in summer months (December-February) to 3.3m in July, providing powerful, clean waves during the winter season. However, wind conditions are challenging, with bad onshore winds (NE-E) prevailing 79-88% of the time, making clean surf sessions rare. The best chance for favorable winds (SW-NW) occurs in May (21% good wind conditions), followed by April and June (19%). Despite larger winter swells, the wind factor limits optimal surfing days, whereas summer (December-March) sees smaller but more manageable swells with similarly poor winds. For advanced surfers seeking bigger waves, May to August is the prime window, but patience is required for those rare clean, offshore days. Early mornings or late evenings may offer brief periods of lighter winds, especially during transitional months like April and May. Overall, Kommetjie is a heavy, powerful wave best suited for experienced surfers, with winter delivering the most size and consistency, albeit with challenging wind conditions.

June at Kommetjie delivers powerful and consistent surf, with an average swell height of 3.2m and a strong period of 12.7s, indicating well-organized, long-period groundswell. The dominant swell direction is from the SW and SSW, with a high percentage of waves in the 2-2.5m range (9.9% for SW and 2.94% for SSW) and a significant portion exceeding 2.5m (2.55% for SW, 0.59% for SSW). These conditions create hollow, fast-breaking waves suitable for experienced surfers. However, wind is a limiting factor—only 19% of the time is it ideal (likely light offshore or sideshore). The prevailing winds come from the NW and WNW, often blowing at 20-40kph (4.25-4.69% for NW, 2.5-2.14% for WNW), which can cause choppy or cross-shore conditions. Stronger winds over 40kph (3.25% for NW) may ruin the surf. While swell energy is excellent, wind quality is inconsistent, so watch for rare clean days with lighter NW or W winds for the best sessions.
