Conditions at La Graviere in January
January: Deep-Winter Groundswell Machine
January is peak season at La Graviere, with a mean swell height of 6ft (1.8m) and an average period of 13.0 seconds. The swell window is dominated by WNW (42.7%) and NW (29.3%) directions, sending long-period groundswell straight into the beach. In fact, 38% of all swells reach at least head-high (5ft/1.5m), and more than 17% exceed 6ft (2m). This is the month when North Atlantic bombs - explosive low pressure systems near the western approaches - deliver powerful, pulsing waves to the Aquitaine coast.
Wind quality is generally good, with ideal surfing conditions 36% of the time. Offshore ENE through SE winds account for roughly 29% of observations, while true onshore westerlies are less dominant than in summer. Still, when frontal systems push through, W and WNW winds can turn the beach into messy, wind-blown chaos. Average precipitation is around 3.40 mm/day. With average air temperatures of 7.0°C and water temperatures at 12.4°C, January demands a proper 5/4 hooded suit, but the reward is cold, thumping, well-shaped winter surf.
