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.

July in Sopelana tends to offer small to mid-sized surf, with an average swell height of 0.8m and a decent period of 9.0s. The dominant swell directions are NW, NNW, and WNW, which make up the majority of rideable conditions. Most waves fall in the 0.5-1.5m range, with the best consistency coming from NW swells (29.32% of waves in the 0.5-1m range and 9.11% in the 1-1.5m range). Larger swells (1.5m+) are less frequent but still possible, primarily from NW and WNW directions. Wind conditions are not ideal most of the time, with only 20% of days providing favorable winds for surfing. The prevailing winds are often from the north and west, which can be onshore or cross-shore, creating choppy or less clean conditions. When lighter winds align (typically below 20kph), the surf can be clean and fun, especially for longboarders or those comfortable with smaller waves. Summer crowds and variable wind conditions mean patience is key—early mornings or late afternoons may offer the best windows for cleaner surf.
