Zarautz - surf spot statistics

Zarautz, located on Spain's northern coast, offers consistent surf conditions year-round, but the best months for surfers are typically from October through February. During this period, ground swell dominates, with percentages ranging from 65% in October up to 84% in January, ensuring cleaner and more powerful waves. The mean swell size is also favorable, averaging between 1.2m and 1.7m, peaking in the winter months. Wind conditions improve slightly in these months, with a higher likelihood of good winds (33-34%) compared to the rest of the year. However, bad wind conditions still prevail (66-68%), so checking daily forecasts remains crucial. Spring and summer see a decline in quality, with ground swell dropping significantly from March onward, replaced by wind swell, which becomes dominant from May to August. Swell size diminishes to 0.8-1.0m during these months, and wind conditions worsen, with bad winds occurring over 75% of the time. September marks the transition back to better surf, with ground swell increasing again, though wind reliability remains low. For surfers seeking the strongest, cleanest waves, the winter months are ideal, despite the higher chance of onshore winds, while summer is better suited for beginners due to smaller, less powerful waves.

August in Zarautz offers generally small but rideable conditions with an average swell height of 0.9m and a decent period of 9.3s, providing some energy for surfing. The predominant swell direction is NNW to NW, producing the most consistent waves, particularly in the 0.5-1.5m range, which accounts for the majority of conditions. Larger sets occasionally reach 2m but are rare. Wind conditions are a mixed bag—while 20% of the time winds are ideal (light and offshore), the rest often see onshore or cross-shore breezes, particularly from the NW and WNW at 10-20kph, which can create chop. Early mornings typically offer the cleanest conditions before winds pick up. Advanced surfers may find some punchy peaks on bigger days, but overall, expect smaller, softer waves suited for intermediates or longboarders. Keep an eye on wind forecasts to score those cleaner sessions.
