Cap Sim - surf spot statistics

Cap Sim, Morocco, offers consistent surf conditions year-round, but the best months for surfers are typically from October through March. During this period, ground swell dominates, with percentages ranging from 73% in October up to 93% in January, ensuring powerful and well-organized waves. The average swell height stays above 1.7m, peaking at 2.1m from December to February, making these months ideal for advanced surfers looking for larger, cleaner waves. Wind conditions are also most favorable in autumn and winter, with good wind days occurring at a 42-46% rate from October to January, significantly higher than the summer months. Spring and summer, particularly from April to August, see a shift toward wind swells, which are less consistent and often accompanied by onshore winds, with bad wind conditions exceeding 70% of the time. September marks a transitional month as ground swells begin to increase again, though wave size remains modest. Overall, late autumn and winter provide the most reliable combination of powerful ground swells and manageable winds, while summer is better suited for beginners or those tolerant of choppier conditions.

May at this Moroccan surf spot offers fairly reliable conditions with a dominant swell direction from the northwest and north-northwest, delivering the majority of waves in the 1–2.5m range (peaking at 1.5–2m with 21.11% frequency). The average swell height is 1.7m with a solid 10s period, ensuring consistent, well-formed waves. Smaller swells (0.5–1.5m) are less frequent, and larger sets (over 2.5m) are rare (0.4%). Wind conditions are more variable—onshore winds from the north and northeast are common, with 23% of days providing offshore or light cross-shore winds ideal for surfing. Stronger winds (20–40kph) from N/NNE occur frequently, potentially creating choppy conditions, but lighter winds (0–20kph) still offer clean sessions, especially early morning. Overall, May is decent for intermediates to advanced surfers, with the best days coinciding with favorable winds and mid-sized NW/NNW swells.
