Imsouane - surf spot statistics

Imsouane, Morocco, is a world-class surf spot known for its long, mellow rides, particularly at the famous "Cathedral" point break. The best months for surfing here are typically between October and March, when ground swell dominates, wind conditions are more favorable, and swell size is consistently rideable. During this period, ground swell percentages range from 70% to 93%, with mean swell heights between 1.2m and 1.5m, offering clean, powerful waves ideal for both intermediate and advanced surfers. Wind conditions are also at their best, with good wind days occurring 50-56% of the time, reducing onshore interference. The peak months—December, January, and February—deliver the most reliable surf, combining high ground swell prevalence (88-93%) and decent wind conditions (50-56%). From April onward, the swell transitions to more wind-driven patterns, resulting in a drop in quality, particularly from May to September when wind swell dominates (60-89%) and mean swell size dips to 1.0-1.3m. Summer months (June-August) are the least consistent, with weaker swells and more frequent onshore winds, though occasional days may still be surfable. For those seeking the best balance of swell consistency, size, and favorable winds, targeting the autumn and winter months (October-February) will maximize the chances of scoring Imsouane’s legendary waves at their best.

October in Imsouane offers consistent surf with an average swell height of 1.2m and a solid period of 11.6s, providing well-organized, rideable waves, ideal for intermediate to advanced surfers. The dominant swell directions are NW and WNW, accounting for the majority of surfable conditions, with waves frequently in the 0.5-2.5m range—peak energy is between 1-2.5m, delivering powerful, clean walls suited for longboarders and high-performance surfing. Offshore winds (light NE to E) are present 50% of the time, ensuring clean faces, while onshore WSW to W winds occasionally disrupt conditions but remain manageable below 20kph. Expect larger swells (>2m) about 10% of the month, mostly from NW/NNW, offering more challenging sections. Wind speeds stay below 30kph for over 90% of the month, minimizing choppy interference. Overall, October is a reliable month with a mix of playful mid-sized waves and occasional powerful sets, best capitalized on dawn patrol or late afternoon when winds are lightest.
