Ile d'Oleron - Chassiron Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Ile d'Oleron - Chassiron that coincided with light winds or offshore conditions through a typical northern hemisphere spring and is based upon 8052 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 red represents the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was W, whereas the the most common wind blows from the NNW. 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 23% of the time, equivalent to 21 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere spring but 7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 7%, equivalent to (6 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Ile d'Oleron - Chassiron is exposed to open water swells, we think that that clean surf can be found at Ile d'Oleron - Chassiron about 23% of the time and that surf is spoilt by onshore wind 56% of the time. This is means that we expect 72 days with waves in a typical northern hemisphere spring, of which 21 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.
