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.

December at Devil's Rock, Morocco, delivers consistent surf with an average swell height of 1.4m and a strong 12.8s period, ensuring well-formed, powerful waves. The dominant swell direction is from the WNW and NW, accounting for the majority of rideable conditions, with waves often in the 1-2.5m range (peaking at 1.5-2m about 7.5% of the time). Smaller pulses (0.5-1.5m) are frequent, but larger sets (2m+) do occur, particularly from the NW and NNW, offering occasional overhead opportunities. Wind conditions are favorable 53% of the time, typically light to moderate (0-20kph) and offshore or cross-offshore from the E to NE sectors, which keeps the faces clean. However, stronger winds (20-30kph) from the N to ENE can occasionally create chop, though they’re less frequent. The spot handles larger NW swells well, but the best sessions are likely when mid-period WNW energy aligns with lighter easterly winds—expect plenty of punchy, lined-up walls ideal for intermediate to advanced surfers. Keep an eye on wind forecasts, as the wrong direction can quickly degrade conditions. Overall, December is a reliable month for quality waves here.
