Devil's Rock - surf spot statistics

Devil's Rock in Morocco offers consistent surf conditions year-round, but the best months for surfers are from November through February when the swell quality and wind conditions are most favorable. During these months, the ground swell percentage is high (77–93%), meaning powerful, clean waves generated by distant storms dominate, while wind swell (6–19%) and no-swell days (1–3%) remain minimal. The mean swell size ranges between 1.3–1.5m, providing solid wave faces for intermediate to advanced surfers. Wind conditions are also most manageable in this period, with good wind days (offshore or light cross-shore) occurring 47–53% of the time, peaking in December and January. Late autumn and winter see the best balance between swell consistency and manageable winds, though even in peak season, bad wind days (onshore or strong cross-shore) still occur around 47–53% of the time, requiring selective timing. From March to October, conditions gradually deteriorate. Ground swells decline significantly (down to 9% in July), and wind swells or smaller mixed swells take over, leading to less powerful and sometimes choppier waves. April through September sees the worst wind conditions, with bad winds (66–75% of days) frequently disrupting wave quality. Summer months (June–August) have the smallest swells (1.0–1.1m) and the highest wind swell influence, making sessions inconsistent. September and October mark a transitional period, with ground swells rebounding (46–69%) and wind conditions slowly improving, though still not as reliable as winter. For surfers prioritizing quality over frequency, the window from November to February is prime, offering the strongest swells and the highest likelihood of clean conditions. Outside this period, expect smaller, wind-affected waves with occasional exceptions in early autumn or late spring. Advanced surfers may still score good sessions in shoulder months like October or March, but consistency drops noticeably compared to winter’s peak.
