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.
