Belle Ile Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Belle Ile that coincided with light winds or offshore conditions over a normal northern hemisphere winter. It is based on 6931 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 represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the largest spokes, was W (which was the same as the dominant wind direction). 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 17% of the time, equivalent to 15 days. Open water swells exceeding >3m (>10ft) only occur 1.0% of the time in a typical northern hemisphere winter, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (7 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Belle Ile is exposed to open water swells, we calculate that clean surf can be found at Belle Ile about 17% of the time and that surf is blown out by onshore wind 51% of the time. This is means that we expect 62 days with waves in a typical northern hemisphere winter, of which 15 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.
