Zurriola - surf spot statistics

Zurriola in Spain offers the most consistent surf conditions during the winter months, particularly from October through February, when ground swell dominates with percentages ranging from 65% to 85%. The mean swell size during this period averages between 1.2m and 1.6m, providing solid wave energy for intermediate to advanced surfers. However, wind conditions are less favorable in these months, with bad onshore winds occurring 65–68% of the time, peaking in December and January. The best window for cleaner conditions is typically in October and November, when good wind days reach 32–35%. Spring (March–May) sees a gradual decline in ground swell (40–76%) and an increase in wind swell, while summer (June–August) delivers smaller, less reliable waves (0.8m mean size) dominated by wind swell, coupled with poor wind conditions (79–84% bad winds). September marks the transition back to better ground swell (47%) and slightly improved winds (26% good), making early autumn a reasonable alternative if winter conditions are too crowded or unruly. For the most powerful and consistent surf, target October–February, but expect challenging winds—early sessions or sheltered spots may help mitigate this. Summer is best suited for beginners due to smaller waves, though wind interference remains an issue.

January at Zurriola offers solid surfing conditions, with an average swell height of 1.6m and a strong period of 13.1s, indicating clean, well-spaced waves. The dominant swell directions are from the northwest and north-northwest, which produce the highest percentage of surfable waves, particularly in the 1-2.5m range. The WNW and NW directions contribute the most to larger swells (over 1.5m), making up a significant portion of the quality surf days. Wind conditions are favorable for surfing 33% of the time, typically when winds are light (0-20kph) and offshore or sideshore. However, stronger winds from the south and southwest can occasionally disrupt conditions. Overall, January provides a good mix of rideable waves, with peak opportunities occurring when swell direction aligns with lighter winds—ideal for intermediate to advanced surfers.
