Anse de Lesconil Swell Statistics, All Year: Surf with Light or Offshore Winds
This image shows only the swells directed at Anse de Lesconil that coincided with light winds or offshore conditions over a normal year and is based upon 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell occurs.
The diagram implies that the dominant swell direction, shown by the longest spokes, was W, whereas the the prevailing wind blows from the WNW. 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 29% of the time, equivalent to 106 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (22 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Anse de Lesconil is slightly protected from open water swells, we estimate that clean surf can be found at Anse de Lesconil about 29% of the time and that surf is messed up by onshore wind 36% of the time. This is means that we expect 237 days with waves in a typical year, of which 106 days should be surfable.
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.
