Belharra - surf spot statistics

Belharra, France, is renowned for its powerful and consistent ground swells, making it a prime destination for advanced surfers. The best months for surfing here are from November through February, when ground swell dominates (84-88% of the time) with mean swell sizes around 1.8-1.9m. These months also see relatively better wind conditions compared to the rest of the year, particularly November and December, where good wind conditions occur 56% of the time—though even then, offshore winds are not guaranteed, and bad winds still prevail 44-64% in winter. January and February maintain strong ground swells but slightly worse wind stats (37-36% good winds). March marks a transition, with ground swell dropping to 79% and mean size decreasing to 1.6m, while poor wind conditions become more frequent (68%). From April to September, conditions deteriorate significantly for high-performance surfing. Ground swells decline sharply (down to 19-29% in summer), replaced by wind swells, and swell size drops to 1.0-1.3m. Wind conditions are largely unfavorable (bad winds 70-82% of the time), making summer months less reliable. October shows a recovery, with ground swell rising to 66% and swell size increasing to 1.4m, alongside improving wind stats (40% good conditions). For the most consistent, powerful waves with a reasonable chance of favorable winds, late autumn to early winter (November-December) is the optimal window, though dedicated surfers may still score in January-February despite the wind challenges. The spot is least appealing from May to August due to weak swells and onshore winds.

January at Belharra offers solid surf conditions with an average swell height of 1.9m and a strong 13.0s period, providing powerful, well-organized waves. The dominant swell direction is from the NW to WNW, contributing the majority of rideable waves (over 60% of swells in the 1-2.5m range), which aligns well with the spot’s orientation. Wind conditions are favorable 37% of the time, typically light to moderate (under 20kph) from the N to NE quadrant, creating offshore or cross-offshore effects that groom the lineup. However, stronger winds (20-50kph) from S to SW directions can occasionally disrupt conditions, particularly when paired with larger swells. Expect consistent, mid-sized to large waves ideal for experienced surfers, though wind quality is hit-or-miss—patience or timing sessions around calmer mornings will maximize opportunities. Bigger days (2m+) with clean winds are less frequent but deliver world-class barrels.
