Eoropie (Lewis) Swell Statistics, Spring: 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 northern hemisphere spring. It is based on 6580 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the SW. 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 23% of the time, equivalent to 21 days. Open water swells exceeding >3m (>10ft) only occur 1.2% of the time in a typical northern hemisphere spring, 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 proportion of these swells that coincided with expected offshore winds, and given the fact that Eoropie (Lewis) is exposed to open water swells, we estimate that clean surf can be found at Eoropie (Lewis) about 23% of the time and that surf is spoilt by onshore wind 58% of the time. This is means that we expect 74 days with waves in a typical northern hemisphere spring, of which 21 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.
