Betty's Bay - surf spot statistics

Betty's Bay in South Africa is a surf spot that offers consistent ground swells year-round, with minimal wind swells and virtually no days without swell. The best conditions for surfing typically occur from April to September, when ground swell dominance is highest (90-93%) and the mean swell size increases, peaking at 3.0m in June and July. During this period, wind conditions improve slightly compared to other months, with good wind days ranging from 22% in April to 29% in May and June. The larger swells and slightly better offshore winds make these months ideal for experienced surfers seeking powerful, clean waves. The shoulder months of March and October still offer reliable ground swells (85-86% and 80% respectively) but with smaller average sizes (2.2-2.4m) and fewer favorable wind days. From November to February, swell size decreases further (2.2-2.3m), and wind conditions are least favorable, with only 13-17% of days having good winds. While surfable waves are almost always present due to the strong ground swell consistency, surfers should prioritize the autumn and winter months (April-September) for the best combination of swell size, power, and marginally improved wind conditions. The spot is rarely flat, but the quality and size of waves are significantly better in the mid-year months.

October at Betty's Bay delivers solid surf conditions with a dominant swell from the southwest, producing consistent waves averaging 2.4m and a strong period of 11.9s, ensuring powerful, well-formed waves. The majority of swells fall in the 1.5–2.5m range, with the SW direction contributing the largest share, offering clean, punchy waves ideal for experienced surfers. Wind conditions are hit-or-miss, with only 16% of the time providing ideal offshore (easterly) winds, while the rest often sees onshore or cross-shore breezes, particularly from the ESE to SE, which can create choppier conditions. The best sessions will come when winds swing ENE or lighter SE, aligning with the SW swell for groomed faces. Expect larger, more powerful days when the swell pushes into the 2.5m+ range, though these are less frequent. Overall, October is reliable for robust surf, but wind luck plays a big role—watch for those cleaner early mornings or protected spots.
