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.

April at La Gravière offers surfable conditions, though with some variability. The average swell height is 1.4m with a solid period of 11.3s, indicating well-formed and powerful waves, particularly when the dominant WNW and NW swells align with the break. These directions contribute the most to rideable waves, with WNW swells (1.5–2.5m) occurring frequently and providing the best energy. Smaller W and NW swells (1–1.5m) are also common, offering more manageable but still punchy waves. However, expect some inconsistency, as smaller swells (0.5–1m) from multiple directions dilute the mix. Wind conditions are favorable 31% of the time, typically when light offshore (E-NE) or light cross-shore winds prevail. Stronger onshore winds (W-WSW) are more frequent and can disrupt conditions, especially when speeds exceed 20kph. For advanced surfers, the best sessions will come from clean WNW groundswells with light offshore winds—expect fast, hollow sections when these elements align. Mid-sized NW swells can also deliver fun, rippable walls. Patience may be needed, as wind and swell direction variability means only about a third of days provide ideal surfing.
