Windmills_1 Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at Windmills_1 that coincided with light winds or offshore conditions through a typical January. It is based on 2868 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 red represents biggest swells greater than >3m (>10ft). In each 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 largest spokes, was NNW, whereas the the prevailing wind blows from the E. 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 10 days. Open water swells exceeding >3m (>10ft) only arise 2% of the time in a typical January, equivalent to just one day but 17% of the time we expect swell in the range 2-3m (6.5-10ft) 17%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Windmills_1 is slightly protected from open water swells, we calculate that clean surf can be found at Windmills_1 about 31% of the time and that surf is blown out by onshore wind 54% of the time. This is means that we expect 26 days with waves in a typical January, of which 10 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.
