Anse de Vauville Swell Statistics, November: Surf with Light or Offshore Winds
This image shows only the swells directed at Anse de Vauville that coincided with light winds or offshore conditions through a typical November and is based upon 2387 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red represents largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell was forecast.
The diagram suggests that the prevailing swell direction, shown by the longest spokes, was W, whereas the the most common wind blows from the WSW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 1.8% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal November. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Anse de Vauville is exposed to open water swells, we estimate that clean surf can be found at Anse de Vauville about 1.8% of the time and that surf is blown out by onshore wind 36% of the time. This is means that we expect 11 days with waves in a typical November, of which 1 days should be clean enough to surf.
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
