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.

In August, Zurriola typically offers small to medium-sized waves with an average swell height of 0.8m and a decent period of 9.4s, indicating relatively clean and organized conditions. The predominant swell direction is from the NW and NNW, contributing to the majority of rideable waves, particularly in the 0.5-1.5m range, which is ideal for intermediate surfers. However, larger waves (over 1.5m) are less frequent, making it more suitable for those who prefer smaller, manageable surf. Wind conditions are favorable for surfing only 19% of the time, with light to moderate winds (0-20kph) being the most common, though stronger winds from the NW and W can occasionally disrupt conditions. Overall, August at Zurriola is best suited for surfers looking for relaxed sessions with smaller, cleaner waves, though wind and swell consistency may require patience for optimal sessions.
