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.

August in Cap Sim, Morocco, delivers fairly consistent surf with an average swell height of 1.5m and a decent period of 8.7s, providing well-formed, rideable waves. The swell is predominantly from the NNW direction, with the highest frequency (33.13%) in the 1-1.5m range and a notable 32.33% in the 1.5-2m range—ideal for intermediate to advanced surfers. Larger sets occasionally reach 2-2.5m (9.98%), adding power for those seeking more challenge. Wind conditions are less favorable, with only 27% of the time being ideal for surfing. The prevailing winds come from the NNE and N directions, often blowing at 10-30kph, which can create choppy or cross-shore conditions. Stronger winds (>20kph) occur frequently, particularly from NNE (24.15%), potentially disrupting wave quality. Surfers should aim for early sessions when winds are lighter, as the best conditions coincide with periods of NW or NNW winds at lower speeds. Overall, August offers consistent, mid-sized waves, but wind interference limits ideal surf days to roughly a quarter of the month.
