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.

In September, Sopelana offers decent surf conditions with an average swell height of 1.0m and a solid period of 10.4s, ensuring clean, well-spaced waves. The primary swell directions are NW, NNW, and WNW, contributing to around 85% of the waves, with the best energy coming from the NW—delivering the majority of waves in the 0.5-2.5m range. Larger sets (1.5m+) are less frequent but occur, mostly from NW and WNW. Wind conditions are variable, with only 28% ideal for surfing (typically light offshore or sideshore NE-E winds). However, stronger onshore W-WSW winds appear occasionally, potentially chopping up conditions. Overall, September provides consistent surf, best on NW swells with favorable winds, though patience may be needed for clean sessions.
