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.

February at Betty's Bay delivers consistent surf with an average swell height of 2.2m and a solid period of 11.8s, providing powerful, well-spaced waves. The dominant swell direction is from the SW, contributing to 70.6% of waves in the 1.5m+ range—ideal for intermediate to advanced surfers. SW swells between 1.5–2.5m are particularly frequent (48.6%), while larger sets over 2.5m occur 1.8% of the time. Wind conditions are less favorable, with only 13% of days offering ideal offshore (E/ENE) or light cross-shore winds. Easterlies (E/ESE/SE) are prevalent but often too strong (20–40kph in 25.5% of cases), creating choppy conditions. SSW-WSW winds (lighter and more manageable) occur 18.4% of the time. Expect consistent, mid-sized SW swells with occasional cleanup days when winds align, but prepare for frequent onshore wind interference. A wetsuit is advisable due to cool summer upwellings. Prime sessions are early mornings before easterlies pick up.
