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.

In September, Gilleleje Havn typically offers small to moderate surf conditions with an average swell height of 0.6m and a relatively short period of 4.0s, indicating mostly weak to average energy waves. The majority of swells come from the W, NW, and NNW directions, with the highest frequency of rideable waves (1.5m+) occurring from the WSW and WNW directions. However, waves over 1.5m are rare, making the spot better suited for beginners or longboarders during this month. Wind conditions are challenging, with only 4% of the time providing ideal offshore or light cross-shore winds for surfing. The most unfavorable winds come from the E-SE sectors, which are often onshore, while stronger winds (20-30kph+) from the W-WSW can create choppy conditions. Experienced surfers will need patience for the occasional clean, waist-high sessions, usually when wind shifts to a favorable NW or N direction. Overall, September is not the most consistent month for quality surf, but there are still opportunities for mellow sessions with the right wind-swell combo.
