Gilleleje Havn - surf spot statistics

Gilleleje Havn in Denmark is a windswell-dominated spot with very limited ground swell influence, rarely exceeding 1% even in December. The best months for surfers are typically late autumn to early winter (October to December), when wind swell frequency peaks around 48-53%, and mean swell sizes reach 0.7-0.8m. However, wind conditions are far from ideal, with good offshore or cross-offshore winds occurring only 3-4% of the time, while onshore or unfavorable winds dominate 94-97% of the year. Swell consistency improves slightly in winter, but the small average wave heights (rarely over 0.8m) and poor wind alignment make this spot challenging for high-performance surfing. Summer months (June-August) see similarly low swell sizes (0.5-0.6m) with marginally better wind conditions (6% good winds), but the high frequency of no-swell days (62-66%) limits surfable opportunities. Overall, Gilleleje Havn is a fickle, wind-dependent spot with the most rideable waves in October-December, though even then, conditions are often small and onshore. Surfers should prioritize storm-driven swells in late autumn when the rare combination of adequate swell and acceptable winds might align.

May in Gilleleje Havn tends to offer generally small and inconsistent surf, with an average swell height of just 0.5m and a below-average period of 3.6s, indicating weak, crumbly waves that lack power. The swell direction is most frequently from the NW and NNW, though most waves are under 1m, with only a small percentage exceeding 1.5m (primarily from SW to NW directions). Wind conditions are challenging, with only 4% of the time being ideal for surfing—typically when light offshore winds from the E to SSE align with small swells. However, stronger onshore winds from the W to SW are more common, creating choppy and blown-out conditions. The spot rarely sees clean, rideable waves in May, and when it does, it’s usually small, weak, and short-lived. Advanced surfers will find it underwhelming, while beginners may struggle with the inconsistency and wind-affected conditions. For decent sessions, patience and precise timing are key.
