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.

November at Anne Avenue delivers consistent surf with an average swell height of 2.6m and a solid 11.2s period, indicating powerful, well-spaced waves. The dominant swell direction is from the SW (25.5% of waves over 2m), followed by SSW (10.3%) and S (3.0%), providing clean, organized walls when paired with the spot's setup. Wind conditions are challenging, with only 14% of days offering ideal offshore (E to SE) or light cross-shore breezes. However, strong onshore WSW winds (16.8% occurrence, often 20-40kph) frequently degrade conditions. Expect the best sessions during rare E/ENE wind events, particularly when SW swell combines with light easterlies—these days produce premium, hollow waves. Mid-range 1.5-2.5m swells from S-SSW offer more frequent ridable days (12-24% occurrence) but require precise wind timing. Advanced surfers will find November rewarding, especially during early mornings before strong afternoon onshores develop.
