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.

July at Cape St Francis delivers consistent, powerful swells with an average height of 3.1m and a solid 12.5s period, making it prime for experienced surfers. The swell is predominantly from the SW and SSW directions, which aligns well with the break, producing clean, well-defined waves. Over 70% of swells exceed 1.5m, with a significant portion (over 20%) surpassing 2.5m—ideal for those seeking size and energy. However, wind conditions are hit-or-miss: only 16% of the time is the wind ideal (light offshore or cross-offshore from the E/ENE). WSW and W winds (often 20-50kph) dominate, causing choppy or blown-out conditions. SW winds, while common, can sometimes groom the waves if not too strong. Expect challenging paddle-outs due to the swell power, and prioritize sessions with lighter E/ENE winds for cleaner faces. Winter wetsuits (4/3mm or thicker) are essential in the chilly water. Overall, July offers high-quality waves for advanced surfers, but patience with wind and swell timing is key.
