Conditions at La Graviere in May
May: Groveling Before the Summer Lull
May continues the downward trend with an average swell height of just 3ft (1.0m) and an average period of 10.1 seconds. The swell direction becomes increasingly NW-dominant, with NW at 50.1% and WNW at 40.8%. This keeps some wave energy in the water, but the size is marginal: over half of all swells sit below 1m, and only about 3% top the 2m mark. Longboard-friendly and fun-sized days are common when a solid NW swell lines up with the sandbars.
Wind quality is the main antagonist. Ideal conditions drop to 22%, while onshore and cross-shore W, WNW, NW and NNW flow collectively occupies nearly half of the wind spectrum. Afternoons often deteriorate into bumpy, sea-breeze affected mushy waves. Yet on a crisp morning with an offshore E or ENE wind and a waist-to-chest-high NW swell, La Graviere can still be wonderfully rippable. Precipitation averages 2.71 mm/day. Water temperatures rise to 16.3°C and air reaches 15.3°C - a pre-summer preview.
