Still Bay - surf spot statistics

Still Bay in South Africa offers consistent surf with year-round swell, as the data shows no months without waves. Ground swell dominates throughout the year, peaking from June to August (85–90%), providing cleaner, more organized waves compared to wind swell. The best months for surfers are between May and August when ground swell is strongest, averaging 2.1–2.2m, and wind conditions improve significantly—good winds occur 35–37% of the time, far better than the summer months (12–19%). During winter (May–August), offshore winds are more frequent, though still challenging (63–65% bad winds). Summer (December–February) has smaller swells (1.9–2.0m) and poor wind conditions (85–88% onshore), making it less ideal. Autumn (March–April) and early spring (September) are transitional, with decent ground swell (77–81%) but worsening winds (19–24% good). Overall, mid-year offers the best mix of size, swell quality, and cleaner winds, while summer is less reliable due to onshore dominance. Advanced surfers will find the biggest and cleanest waves in June and July, though wind luck is still needed.

December in Still Bay delivers solid surf conditions with an average swell height of 2.0m and a healthy period of 11.1s, ensuring well-formed, powerful waves. The dominant swell directions are SSW and SW, which account for the majority of waves in the 1.5–2.5m range, providing consistent, high-quality surf. The wind is ideal for surfing only 14% of the time, with the biggest challenge being easterly (E, ESE) and strong winds (20–40kph) that can create choppy conditions. However, when winds are lighter or offshore (SSE to SW), the waves clean up nicely, offering excellent rides. Overall, expect a mix of punchy, powerful days and some wind-affected sessions, but with enough quality swells to make it worth paddling out.
