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.

February at Zurriola offers decent surf conditions with an average swell height of 1.6m and a solid period of 13.0s, ensuring well-formed, powerful waves. The majority of swells come from the NW, WNW, and NNW directions, with the best wave energy concentrated in the 1–2.5m range, particularly between 1.5–2m (9.96% for NNW). Smaller swells (0.5–1.5m) are frequent but less impactful. Wind conditions are favorable for surfing only 32% of the time, with the most common onshore winds blowing from the S, SSW, and SW, often in the 10–30kph range, which can create choppier conditions. Offshore winds, though less frequent, occur from the N-NE and ENE, providing cleaner faces. Expect a mix of surfable days, though consistency depends on wind alignment—when winds are light or offshore, the spot can produce quality surf with its dominant NW swells delivering punchy, lined-up waves. Bigger days (2m+) are rarer but possible, particularly from the WNW and NW. Overall, February is a mid-range month with potential for good sessions if timed around wind shifts.
