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 January, Anne Avenue typically offers solid surfing conditions with an average swell height of 2.5m and a strong average period of 11.3s, indicating powerful, well-formed waves. The swell direction is predominantly from the SW (21.63% of waves in the 2-2.5m range), with significant contributions from SSW and S directions, providing consistent energy and rideable waves. However, wind conditions are less favorable for surfers, with only 14% of wind conditions being ideal—typically when winds are light or offshore. ENE and E winds are prevalent, often blowing at 20-30kph (4.35% and 4.69%, respectively), which can create choppy or less clean surface conditions. WSW winds also feature prominently at higher speeds (5.11% at 20-30kph), further disrupting wave quality. While the swell delivers size and power, wind interference limits the number of truly clean sessions. Advanced surfers will find the best opportunities early in the day or during rare offshore wind windows, making January a mixed but occasionally excellent month for surfing at this spot.
