Mundaka - surf spot statistics

Mundaka is a world-class left-hand river mouth wave that thrives on powerful, well-organized ground swell and favorable wind conditions. The data shows that the best months for surfing here are from October through March, when ground swell dominates (65-85% occurrence), mean swell heights range from 1.3m to 1.8m, and the likelihood of good wind conditions peaks at 30-31% (compared to the summer lows of 19-23%). Winter months, particularly December to February, offer the most consistent and powerful swells, though wind conditions remain challenging (69-72% bad winds). Spring and summer see a sharp decline in quality, with increasing wind swell dominance, smaller waves (0.8-1.2m), and worse wind odds (74-81% unfavorable). September marks the transition back to better conditions, while April through August are generally inconsistent due to higher wind swell influence and onshore winds. For experienced surfers targeting Mundaka's legendary barrels, the prime window is autumn through early winter when the Atlantic swell engine is most active and wind chances slightly improve, despite still being predominantly marginal. The spot's reliance on precise sandbar formation means these stats only tell part of the story, but the trend clearly favors late fall and winter for the biggest, cleanest sessions.

February at Mundaka offers solid surf conditions with an average swell height of 1.7m and a healthy 12.8s period, indicating consistent, well-formed waves. The swell is predominantly from the northwest and north-northwest, which aligns well with the spot’s setup—around 15% of the time, waves reach the ideal 1.5-2.5m range from these directions, while larger sets (over 2.5m) occur roughly 1.3% of the time, mostly from NW and NNW. Wind conditions are variable, with ideal offshore or light winds occurring 30% of the time, typically when winds come from the east or northeast at under 20kph. However, stronger onshore winds from the south and southwest, especially in the 20-40kph range, can disrupt conditions about 15-20% of the time. Overall, February delivers reliable, powerful waves with a mix of clean and choppy days—best suited for experienced surfers who can handle the occasional sizeable swell and shifting winds.
