Cape Town - surf spot statistics
Cape Town seasonal overview
Cape Town offers consistent surf year-round, with the best conditions typically found from April to August. During these months, ground swell dominates (90-93% of the time), providing clean, powerful waves with minimal wind interference. The mean swell size increases from 2.5m in April to 3.1m in June and July, making these peak months for experienced surfers seeking larger, more challenging waves. Wind conditions improve slightly in April and May, with good wind days occurring around 28-29% of the time, though bad winds still prevail most days (71-72%). Winter months (June-August) maintain strong swell (3.0-3.1m) but see a slight drop in favorable winds (24% good wind days). The shoulder months of March and September still deliver solid surf (86-87% ground swell, 2.4-2.8m) but with fewer clean wind days. Summer (December-February) brings smaller swells (2.4m) and significantly worse wind conditions, with only 19-21% good wind days, making it less ideal for surfers prioritizing quality. Overall, advanced surfers will find the most reliable waves from autumn through winter, particularly April-July, when larger swells and slightly better wind windows align. However, strong offshore winds are relatively rare year-round, so patience is key when chasing ideal sessions in Cape Town.

Conditions at Cape Town in July
July in Cape Town delivers solid winter swells, averaging 3.1m with a consistent 12.7s period, making it a powerful and well-lined-up season for experienced surfers. The dominant swell direction is from the SW to SSW, with the highest frequency of waves in the 2-2.5m range (10.13% SW, 5.10% WSW) and a significant presence of larger waves over 2.5m (2.55% SW). This indicates consistent, high-energy groundswells. Wind conditions are hit-or-miss, with only 24% of days offering ideal offshore or light cross-shore winds (typically NW or NNW). However, strong onshore winds (20-50+ kph from SE to NW) are common, particularly from the NW quadrant, which can degrade wave quality. Expect a mix of epic, clean days when winds align and challenging, choppy sessions when onshore flow kicks in—best suited for surfers comfortable with sizable, powerful waves and variable wind conditions.
