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.

March in Gilleleje Havn offers generally small surf conditions with an average swell height of 0.6m and a short period of 3.9s, making it mostly suited for beginners or longboarders. The most consistent and rideable waves come from the west-northwest (WNW) and west (W) directions, where wave heights occasionally reach 1.5-2.5m, though the majority are under 1m. Swells from the east (E, ENE) are frequent but tend to be weaker and smaller, often below 0.5m. Wind conditions are challenging, with only 3% of winds being ideal for surfing—typically lighter winds from north or northeast directions that don’t blow out the waves. Stronger winds (20-40kph) are common from the southwest (SW, WSW), which can create choppy or unfavorable conditions. For surfers, the best chances arise when WNW swells coincide with light offshore or cross-shore winds, but such days are rare. Expect mostly small, weak surf with occasional clean sessions when wind and swell align.
