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.

July at La Gravière offers variable but often surfable conditions, though not consistently firing. The average swell height is 1.0m with a decent period of 9.3s, indicating reasonably clean and organized waves when swells arrive. Most swells come from the W to NW sector, accounting for the majority of wave energy, particularly in the 0.5-2.5m range. The W and WNW directions dominate, with WNW contributing the most significant percentage of waves in the 0.5-2.5m range (peaking at 1-1.5m). Larger swells (over 2m) are rare but possible, mostly from WNW. Wind conditions are best for surfing only 24% of the time, with prevailing winds from the W and NW often blowing in the 10-30kph range, which can create chop or cross-shore effects. Light winds (under 10kph) are more common from the NE to ESE, but these directions rarely coincide with meaningful swell. For surfers, expect smaller, manageable waves with occasional clean sessions when winds align—typically early mornings or during favorable wind switches. It’s not a high-season month, but patience and timing can reward with fun, if not epic, sessions.
