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.

September in Zarautz offers fairly consistent surf conditions with an average swell height of 1.0m and a solid period of 10.5s, providing clean, well-spaced waves. The most dominant swell directions are NNW, NW, and WNW, accounting for the majority of waves over 0.5m, with a notable percentage in the 1-1.5m range and occasional larger sets up to 2.5m. Smaller swells from the north and west also contribute, but their impact is minimal. Wind conditions are generally favorable 27% of the time, with light to moderate speeds (0-20kph) from the north and northwest being the most common. However, stronger winds (20-30kph) occasionally come from the west or southwest, which can create choppier conditions. Overall, September delivers a mix of manageable waves for intermediate surfers, with the best sessions occurring when winds are light from the north or northwest, aligning with the dominant swell direction for cleaner, more organized surf. Expect some great days with rideable waves, though larger swells remain infrequent. Keep an eye on wind forecasts for optimal sessions.
