Cape St Francis - surf spot statistics

Cape St Francis in South Africa is a consistent surf spot with reliable swell year-round, primarily fueled by ground swells, which dominate across all months. The best time for surfers is during the winter and early spring months (May to September) when ground swell percentages peak (87–90%), and average swell sizes are largest (2.9–3.1m). These months offer powerful, clean waves thanks to dominant ground swells, though wind conditions are less favorable, with bad winds (onshore or cross-shore) occurring 83–85% of the time. The shoulder months (April, October) still provide solid swell (2.7m in April, 2.8m in October) but with similarly challenging winds. Summer (December–March) sees slightly smaller swells (2.5m) and marginally better wind conditions (good winds 18–19% of the time), though bad winds still prevail (81–82%). While winter delivers the biggest and most consistent waves, the frequent poor winds mean surfers must pick their sessions carefully. If clean conditions align with the strong winter swells, Cape St Francis can offer world-class waves, but patience is key due to the high likelihood of wind interference. In contrast, summer provides fewer perfect days but slightly more manageable winds for those seeking smaller, fun sessions.
