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.

April at Zurriola offers decent surf conditions, though not consistently ideal. The average swell height is 1.1m with a solid 11.2s period, providing reasonably clean and rideable waves. The majority of swells come from the NW, WNW, and NNW directions, which align best with the spot's orientation, delivering the most frequent and sizable waves. Around 64% of swells are between 0.5–2m, with the most common range being 0.5–1.5m (over 50% occurrence). Larger waves (1.5–2.5m) appear about 10% of the time, while anything over 2.5m is rare—ideal for intermediate to advanced surfers when clean. Wind conditions are a mixed bag—only 24% of the time are they favorable (light offshore or sideshore). The predominant winds blow from the NW and W sectors, often in the 10–20kph range, which can create texture or chop, especially in the afternoons. Stronger winds (20–30kph) occur around 15–20% of the time, further reducing quality. Early mornings typically offer the cleanest sessions before onshore winds pick up. For surfers, the best opportunities arise when NW swells meet light E/NE winds, providing groomed, punchy waves. Keep an eye on the tide—Zurriola is tide-sensitive—and prioritize mid-period NW/NNW swells with morning winds under 10kph for the optimal experience.
