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 May, Anne Avenue in South Africa offers solid surf conditions with an average swell height of 2.9m and a solid period of 12.3s, indicating powerful, well-formed waves ideal for experienced surfers. The predominant swells come from the SW to SSW directions, with the highest frequency of waves between 2-2.5m (15.68% from SW) and strong contributions from the 1.5-2m and over 2.5m ranges. These swells are clean and organized, favoring high-performance surfing. However, wind conditions are variable—only 21% of the time are they ideal for surfing, as winds often come from the W to WSW at speeds of 20-50kph, which can create choppy or cross-shore conditions. Light offshore winds (E to SE) are rare but provide the best setup. Expect consistent, powerful surf with occasional wind interference, making it best suited for those comfortable in larger, more challenging waves.
