Anne Avenue - surf spot statistics

Anne Avenue in South Africa is a surf spot that offers consistent swell year-round, with the best conditions typically found between May and September. During these months, the swell is predominantly groundswell (87-90%), which provides cleaner, more powerful waves, and the average swell size peaks at 3.1m. The wind conditions, however, are less favorable, with only 17-21% of days offering good winds, meaning offshore or light winds are relatively rare. Despite this, the reliable swell and larger wave size make this period the prime time for experienced surfers who can handle onshore winds. From October to April, the swell remains consistent but shifts toward a slightly higher percentage of wind swell, particularly in October and November (33-35%). Swell size decreases slightly to 2.5-2.8m, and wind conditions worsen, with good winds occurring only 12-15% of the time. The summer months (December-February) still see solid groundswell (69-74%), but the high frequency of bad winds (85-88%) makes wave quality less reliable. For surfers prioritizing wave power and consistency, the winter months (May-September) are ideal, though wind conditions are challenging. If you can tolerate onshore winds and prioritize bigger swells, this is the window to target. The rest of the year is surfable but less predictable due to wind interference. Advanced surfers will find the best opportunities in mid-year, while less-experienced riders may prefer smaller days in the shoulder seasons when winds occasionally cooperate.

In August, Anne Avenue in South Africa offers solid surf conditions with an average swell height of 3.1m and a strong average period of 12.3s, indicating powerful, well-spaced waves. The swell predominantly arrives from the southwest (SW), which accounts for the largest share of waves, particularly in the 2-2.5m and over 2.5m ranges—ideal for advanced surfers. Cleaner conditions (17% of the time) occur when winds are favorable, though winds are often an issue, particularly from the W to WSW, bringing stronger gusts (20-50kph) that can create choppy or cross-shore conditions. The spot handles bigger swells well, but wind quality is the limiting factor, requiring patience for cleaner sessions. Overall, August delivers consistent, sizable surf, but optimal conditions are somewhat rare due to wind interference.
