Hanstholm - surf spot statistics

Hanstholm, Denmark, experiences a mix of wind swell and ground swell throughout the year, with the best conditions typically occurring in the autumn and winter months. The swell is predominantly wind-driven, with ground swell rarely exceeding 10% of total swell activity. The mean swell size peaks in December and January at 1.3m, dropping to its lowest in April through August at around 0.8m. The best months for surfers are November through February, when larger swells (1.0–1.3m) coincide with slightly more favorable wind conditions, though the overall wind conditions remain challenging, with good winds occurring only 7–9% of the time. The worst wind conditions are seen from May to September, where bad winds dominate 93–94% of the time, paired with smaller swells. While Hanstholm is surfable year-round, advanced surfers will find the most consistent waves in late autumn and winter, despite the often poor winds. Spring and summer offer smaller, weaker swells and are better suited for beginners or longboarders. If you're chasing bigger, more powerful waves, prioritize November to February, but be prepared for strong onshore winds and cold conditions.

Hanstholm in September typically offers small to mid-sized swells with an average height of 1.0m and a moderate period of 6.7s, indicating generally manageable but somewhat mushy waves. The most consistent swell directions come from the W, WNW, and NW, where waves in the 0.5-1.5m range are frequent, though larger sets (1.5-2.5m) occur occasionally. Wind conditions are less favorable for surfing, with only 7% of the time featuring ideal offshore or light cross-shore winds. Winds from the W, WSW, and WNW dominate, often blowing in the 20-40kph range, which can create choppy or blown-out conditions. Expect variable sessions: smaller, cleaner waves are possible on rare days with lighter NNE or NE winds, while stronger W-WSW winds will likely degrade wave quality. Overall, September is a mixed bag—surfable, but patience and flexibility are key to scoring the best conditions.
