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.

June in Gilleleje Havn typically offers small, weak surf conditions with an average swell height of just 0.5m and a short period of 3.7s, resulting in minimal energy. The largest waves predominantly come from the NW to WNW directions, where swells occasionally reach 1.5–2.5m, though these instances are relatively rare (1–2% of the time). Most waves are under 1m, with the majority being tiny (0–0.5m) and lacking power. Wind conditions are rarely favorable, with only 4% of days offering ideal light offshore winds. The most common winds are W to WSW at 10–30kph, which often create choppy or blown-out conditions. For surfers, June is generally poor here—expect small, soft waves with onshore winds dominating. It’s a month better suited for beginners or longboarders on the very occasional clean day when a NW swell aligns with lighter winds. Advanced surfers will find little reward unless a rare larger swell arrives.
