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.

April in Sopelana delivers fairly consistent surf conditions with a moderate average swell height of 1.1m and a solid period of 10.9s, offering clean, well-spaced waves. The dominant swell directions are NW, NNW, and WNW, which account for the majority of rideable waves—particularly in the 0.5-2.5m range. These swells provide good shape and power, especially when paired with the longer periods. Smaller swells from the N and NNE contribute occasionally but are less impactful. Wind conditions are a mixed bag, with only 26% being ideal for surfing. The most favorable winds are typically light offshore (NE to E) or light cross-shore, while stronger W, WNW, and SW winds can create choppy or unfavorable conditions. Larger swells (1.5m+) are less frequent but possible, mainly from the NW quadrant. Overall, April offers decent surf with a mix of smaller, playful days and occasional solid sessions, though wind can be a limiting factor. Advanced surfers will find the best windows early in the day before winds pick up.
