Sopelana - surf spot statistics

Sopelana in Spain offers varying surf conditions throughout the year, with the best months typically falling in the winter and early spring. From January to March, the swell is predominantly ground swell (75-84%), which provides cleaner, more organized waves, averaging 1.4-1.6m in size. Wind conditions, however, are less favorable during these months, with only 29-30% of days seeing good offshore or cross-offshore winds. The swell consistency drops noticeably from April onward, with ground swells decreasing to 57% in April and falling below 40% from May to August. During this period, wind swells dominate, and the average swell size diminishes to 0.8-1.1m, making conditions less ideal for advanced surfers. September marks a transitional phase as ground swells start increasing again (45%), while October stands out as a solid month with 64% ground swells and slightly better wind conditions (34% good winds). November and December bring back stronger ground swells (72-79%) and decent wave heights (1.5m), though wind reliability remains inconsistent. Overall, the prime months for quality waves in Sopelana are October through March, with the highest consistency in swell and respectable wave size, despite the wind often being less than perfect. The summer months (May-August) are marginal, with smaller, wind-driven swells and fewer favorable wind days, making them better suited for beginners or longboarders. For serious surfers, the autumn and winter windows provide the best balance of swell power and rideable conditions.

January in Sopelana offers decent surf conditions, though with some variability. The average swell height is 1.6m, paired with a solid 12.8s period, indicating well-spaced, powerful waves—ideal for intermediate to advanced surfers. The majority of swells come from the NW, WNW, and NNW directions, which align best with the spot’s orientation, delivering consistent wave heights between 1-2.5m. Notably, NW swells dominate, with 14.61% of waves in the 1-1.5m range and 10.61% in the 1.5-2m range, ensuring reliable surf. However, smaller or weaker swells from other directions are less frequent. Wind conditions are favorable for surfing only 29% of the time, with lighter winds (0-20kph) from the N, NE, and E being most common. Stronger onshore winds (SSW, SW) can occasionally disrupt conditions, particularly when exceeding 20kph. Overall, January provides solid NW swells and manageable wind periods, making it a worthwhile month for surfers willing to time their sessions around wind shifts.
