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.

December in Imsouane offers consistent surf conditions with an average swell height of 1.5m and a solid period of 12.9s, generating well-organized, powerful waves ideal for intermediate to advanced surfers. The dominant swell direction is from the WNW to NW, contributing to the majority of rideable waves, with heights often ranging between 1-2.5m. Larger sets exceeding 2.5m are less frequent but provide excellent opportunities for experienced riders. Wind conditions are favorable 53% of the time, typically light to moderate (under 20kph) and often offshore or cross-shore from the NNE to ENE, which helps maintain clean, groomed faces. However, stronger easterly winds occasionally occur but are less disruptive due to the spot’s sheltered exposure. Expect a mix of playful mid-sized waves and occasional powerful, hollow sections, making December a reliable month for quality surf in Imsouane.
