Conditions at La Graviere in December
December: Winter Lock-In
December officially locks in the winter season at La Graviere with an average swell height of 5-6ft (1.7m) and an average period of 12.6 seconds. The swell window remains dominated by WNW (39.6%) and NW (32.4%), with a slightly stronger W component (3.8%) than earlier in the winter. More than a third of the swells are head-high or bigger, and long-period groundswell events can quickly turn the beach from clean and lined up to heavy and dredging. It's a month of great potential - and occasional excess.
The cleanest wind statistics of the year tie February, with ideal surfing conditions 38% of the time. Easterly offshore winds - ENE and E combined make up over 16% - are a common response to high pressure over central Europe, providing the classic glassy morning conditions that La Graviere is famous for. When these offshore winds meet a strong NW groundswell, the sandbanks produce fast, barreling beachbreak waves. Precipitation averages 3.60 mm/day. Water temperature drops to 13.4°C and air to 7.7°C; a quality 5/4 suit is essential, but this is the surf you have been waiting for.
