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.

October at Cap Sim offers consistent surf with an average swell height of 1.7m and a solid period of 11.7s, indicating well-organized, powerful waves. The dominant swell direction is from the NW to NNW, with the highest frequency of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. Wind conditions are favorable 43% of the time, primarily light to moderate (under 20kph) from the NNE and N, which often aligns offshore or cross-offshore for clean faces. However, stronger N/NE winds (20-30kph) occur around 15-20% of the time, potentially creating choppier conditions. Smaller days (under 1m) are rare, while larger swells (2-2.5m+) appear frequently enough (15-25% of the time) to challenge experienced riders. Expect a mix of playful mid-sized days and powerful overhead sessions, with the best windows when NW swells meet lighter NNE winds.
