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 May, Zurriola offers generally small but clean surf conditions with an average swell height of 0.9m and a solid period of 10.2s, indicating well-organized, albeit not overly powerful, waves. The dominant swell directions are NW, NNW, and WNW, with the highest frequency of waves in the 0.5-1.5m range, meaning most days see rideable but not heavy surf. Larger swells (1.5m+) are less common, occurring mostly from the northwestern quadrants. Wind conditions are favorable for surfing only 21% of the time, with light to moderate offshore winds (N, NNE, NE) being the most ideal; however, stronger onshore winds from the W and NW can occasionally create choppy conditions. The best windows for clean surf typically coincide with lighter winds from the north or east, but surfers should expect many days with small, soft waves or wind-affected conditions. Overall, May is a decent month for beginners and longboarders, while shortboarders may need patience for the occasional well-shaped, mid-sized NW swell.
