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.

December at Zurriola offers surfable conditions with an average swell height of 1.5m and a solid 12.7s period, providing enough power for intermediate to advanced surfers. The dominant swell directions are from the **WNW, NW, and NNW**, which align best with the beach’s orientation, delivering the most consistent and rideable waves. These directions account for the majority of waves in the **1-2.5m** range—ideal for performance surfing. However, waves over 2.5m are rare (less than 1%), meaning bigger winter swells are not as frequent here as in more exposed spots. Wind conditions are somewhat variable, with **offshore or light winds (0-20kph) occurring 34% of the time**, mainly from the **E to SE directions**, which are ideal for clean faces. However, strong onshore winds from the **S to WSW** can occasionally disrupt the lineup, especially when speeds exceed 20kph (around **15-20% of the days**). Surfers should prioritize early morning sessions when winds tend to be lighter. Overall, December is a decent month for surfing at Zurriola, offering a mix of clean, medium-sized waves when the wind cooperates, though the consistency of good conditions is moderate. It’s not a big-wave destination this time of year but works well for those seeking punchy beachbreak peaks.
