Cap Gris-Nez - surf spot statistics

Cap Gris-Nez is predominantly a windswell-driven spot, with ground swell being almost negligible throughout the year. The best months for surfers are typically late autumn to early spring (October to March), when wind swell frequencies are highest (66-75%) and mean swell sizes peak around 0.8-1.0m. However, wind conditions are challenging year-round, with bad onshore winds dominating (93-96% of the time). The worst months are May to September, where wind swell drops below 55%, no-swell days increase (44-52%), and wave heights average just 0.6-0.7m. Even the best months offer only marginal conditions due to poor wind alignment, making this spot highly inconsistent. Dedicated surfers may find rare clean sessions in winter when windswell is strongest, but overall, Cap Gris-Nez is unreliable compared to more exposed Atlantic breaks. Wind direction and local shelter play a bigger role in surfability than swell size alone here. Expect mostly small, choppy waves with frequent onshore winds regardless of season.
