Flowrider - surf spot statistics

The surf conditions at Flowrider, South Africa, vary throughout the year, with distinct patterns in swell and wind. The best months for surfing are typically from May to August, when ground swell dominates (64-69%) and wind conditions are more favorable (28-33% good wind days). During this period, mean swell sizes range from 2.1m to 2.3m, providing consistent, high-quality waves. June stands out as the peak month, offering the highest ground swell percentage (69%) and the best wind conditions (33% good days).

Summer months (January to March) see mixed conditions, with moderate ground swell (40-54%) but poor wind quality (82-87% bad days). Swell size remains decent (2.0-2.0m), but onshore winds often spoil the surf. If you’re chasing the best waves, target the May-August window for reliable swell, cleaner winds, and bigger waves. Early autumn (April) and late winter (July) can still provide good sessions, but consistency drops significantly toward spring and summer.

August at Flowrider, South Africa, delivers consistent swell with an average height of 2.3m and a strong period of 11.1s, indicating powerful, well-spaced waves.
