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.

June at La Gravière offers generally small to moderate swell conditions, with an average height of 1.1m and a solid period of 9.7s, indicating consistent energy in the waves. The dominant swell direction is from the WNW, accounting for the majority of rideable waves, particularly in the 0.5-2.5m range, with the best quality likely in the 1-1.5m and 1.5-2m brackets (24.55% and 9.88%, respectively). However, bigger days over 2m are rare (under 3% combined). Wind conditions are less favorable, with only 24% of the time offering ideal offshore or light cross-shore winds for surfing. The predominant winds come from the NW and W sectors, often blowing at 10-20kph, which can create chop or sideshore effects. Stronger winds (20-30kph) are present around 15% of the time, mostly from W/NW directions, further reducing clean conditions. Overall, June delivers fun-sized waves with decent period, but wind quality is inconsistent, requiring patience for those pristine sessions. Advanced surfers can find some quality rides on WNW swells when winds align, though larger swells are infrequent.
