Conditions at Parlementia in December
December: Peak Winter Perfection
December is arguably the single best month for surf at Parlementia. The average swell height is a solid 1.7m (5.6ft) and the period is a long, powerful 12.6s. The direction is perfect: WNW (39.6%), NW (32.4%), and NNW (5.0%) combine for a 77% share of all swell from the optimal quadrant. The height distribution is beautifully spread, with a strong showing of 1-1.5m (11.4%), 1.5-2m (10.4%), and 2-2.5m (7.8%) from WNW, meaning Parlementia sees not just inconsistent bombs but regular, rideable, high-quality waves. Wind statistics are the best of the entire year: ideal offshore winds blow a remarkable 51% of the time, and the wind rose shows a dominant S/SSW flow (13.7% and 10.5%) that keeps the beach clean and the faces smooth. On those days, when a deep low sits off the Bay of Biscay and the wind wraps from the southeast, Parlementia delivers some of the heaviest, most powerful beach break waves on the whole French coast. The only downsides are the cold: air temps average 9.9°C, water drops to 13.4°C, and precipitation is high at 3.69 mm/day. But for committed surfers, December is the pinnacle - winter gold.
