Hondarribia, Spain, offers surfable conditions year-round, but the best months for consistent, high-quality waves are from October through March. During this period, ground swell dominates (66-87% occurrence), providing powerful, well-organized waves with mean swell sizes ranging from 1.4m to 1.9m. Winter months (December-February) see the largest swells (1.8-1.9m) and the highest ground swell percentages (82-87%), making them ideal for experienced surfers seeking bigger, cleaner waves. However, wind conditions are less favorable, with bad winds (onshore or cross-shore) occurring 60-65% of the time. Spring (April-June) and summer (July-September) bring smaller swells (1.0-1.3m) and a higher proportion of wind swells, leading to choppier, less reliable conditions. While summer months have slightly better wind stats (40% good winds), the swell quality drops significantly, with ground swells as low as 19% in July. Late autumn (October-November) strikes a balance, offering solid ground swell (66-74%), decent swell size (1.4-1.7m), and marginally improved wind odds (38-40% good winds). For surfers prioritizing size and power, the winter window is best despite the wind challenges, while those seeking a compromise between swell and wind favor October or March-April. Beginners may find summer's smaller waves more manageable, though the prevalence of wind swells reduces overall quality.
