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

This image shows only the swells directed at Ile d'Oleron - La Cotiniere that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 8052 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 largest 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 happens.

The diagram implies that the prevailing swell direction, shown by the largest 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 31% of the time, equivalent to 28 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 predicted offshore winds, and given the fact that Ile d'Oleron - La Cotiniere is exposed to open water swells, we calculate that clean surf can be found at Ile d'Oleron - La Cotiniere about 31% of the time and that surf is blown out by onshore wind 48% of the time. This is means that we expect 72 days with waves in a typical northern hemisphere spring, of which 28 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.
