Cape Town - surf spot statistics

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.

In April, Cape Town offers solid surf conditions with an average swell height of 2.5m and a consistent period of 12.5s, indicating powerful, well-spaced waves. The swell distribution shows that the majority of waves come from the SW (36.7% of waves 1.5m+) and SSW (12.4% of waves 1.5m+), delivering clean, long-period groundswells ideal for advanced surfers. Wind conditions are the main limiting factor, with only 29% of days providing offshore or light cross-shore winds (mostly from SE to SSW under 20kph). However, strong onshore SE to SSW winds (20-40+ kph) are frequent, particularly in the afternoon, which can create choppy or blown-out conditions. The best sessions will coincide with SW swell aligning with lighter ESE to SSE winds early in the day. Bigger sets (2.5m+) occur regularly (16.7% of SW swells), offering hollow, high-performance walls for experienced surfers. Expect longer wait times between sets due to the deepwater nature of the swells. Windswell is negligible, maintaining clean groundswell dominance. While not the most consistent wind-wise, April delivers quality waves when conditions align, especially for those chasing powerful, well-defined lines with fewer crowds than peak season.
