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

The rose diagram shows only the swells directed at Eoropie (Lewis) that coincided with light winds or offshore conditions through a typical December. It is based on 2457 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 show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was NW, whereas the the most common 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 7 days. Expect open water swells to exceed >3m (>10ft) 7% of the time (2 days). Taking into account the proportion of these swells that coincided with forecast 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 blown out by onshore wind 59% 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.
