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.

July at Anne Avenue delivers consistent, powerful surf with an average swell height of 3.1m and a strong 12.5s period, indicating well-spaced, clean waves. The swell direction is predominantly from the SW to SSW (over 75% of waves), producing solid, rideable conditions with the bulk of waves falling in the 1.5–2.5m range (peaking around 2–2.5m). Larger sets exceeding 2.5m occur but are less frequent. Wind conditions are less favorable, with only 20% of days offering ideal offshore/side-offshore winds (typically light E to SE breezes). The majority of winds come from the W to NW at 20–40kph, creating onshore chop and challenging surf. For experienced surfers, July provides powerful, hollow waves when winds cooperate, but expect strong currents and variable wind conditions.
