La Graviere - surf spot statistics

La Gravière in France is a powerful beach break known for its heavy, hollow waves, best suited for experienced surfers. The most consistent and high-quality conditions occur from October through March, when the Atlantic swells are strong and frequent. During these months, ground swells dominate, with percentages ranging from 66% in October to 90% in January, delivering mean swell sizes between 1.5m and 2.1m. Swell consistency is highest in winter, particularly in January and December, when ground swell probabilities peak above 84% and wave heights average around 2.0m or more. Wind conditions are more variable but tend to be most favorable in October, November, February, and December, when good wind days occur around 39–41% of the time. Spring (April–June) and summer (July–September) see a decline in quality, with ground swells becoming less dominant and wind swells or weaker conditions taking over. Swell size drops below 1.5m after March, and adverse winds prevail, with bad wind probabilities exceeding 59% from April onward. September marks a transitional month with improving swell but still inconsistent winds. For powerful, clean waves, the ideal window is late autumn to early winter, particularly October–February, when solid swells meet relatively better wind odds. Summer is generally poor, with small, wind-affected waves. Advanced surfers should target the peak winter months for heavy barrels, though offshore winds are less reliable and require careful timing.

March at La Gravière offers solid surf conditions with an average swell height of 1.8m and a robust 12.4s period, indicating powerful, well-formed waves. The dominant swell direction is from the WNW, contributing the largest share of rideable waves—particularly in the 1.5-2.5m range (28-30% of the time). This direction aligns well with the beach’s orientation, producing quality setups with good energy. The wind is surfable 36% of the time, most frequently blowing lightly (10-20kph) from the W or WNW, which is often offshore or sideshore, ideal for clean faces. However, stronger winds (20-30kph+) from the W/NW can occasionally create choppier conditions. Smaller swells (0.5-1.5m) from the WSW and SW appear occasionally but lack consistency. Overall, March delivers reliable, mid-sized to large waves with decent wind conditions, though surfers should watch for occasional onshore winds affecting quality. Advanced riders will find the best sessions during WNW swells with lighter offshore winds.
