Eoropie (Lewis) Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Eoropie (Lewis) that coincided with light winds or offshore conditions over a normal December. It is based on 2953 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 illustrates largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the biggest spokes, was NW, whereas the the most common 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 22% of the time, equivalent to 7 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Eoropie (Lewis) is exposed to open water swells, we calculate that clean surf can be found at Eoropie (Lewis) about 22% of the time and that surf is blown out by onshore wind 62% of the time. This is means that we expect 25 days with waves in a typical December, of which 7 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.
