Beacon Cove Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Beacon Cove that coincided with light winds or offshore conditions over a normal northern hemisphere winter. It is based on 8485 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 show increasing swell sizes and red illustrates the highest 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 most common swell direction, shown by the biggest spokes, was W, whereas the the dominant 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 15% of the time, equivalent to 14 days. Open water swells exceeding >3m (>10ft) only arise 0.9% of the time in a typical northern hemisphere winter, equivalent to just one day but 6% of the time we expect swell in the range 2-3m (6.5-10ft) 6%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Beacon Cove is slightly protected from open water swells, we estimate that clean surf can be found at Beacon Cove about 15% of the time and that surf is blown out by onshore wind 65% of the time. This is means that we expect 73 days with waves in a typical northern hemisphere winter, of which 14 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.
