Cliff Beach (Lewis) Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Cliff Beach (Lewis) that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 7252 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 illustrate increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In either graph, 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 largest 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 26% of the time, equivalent to 24 days. Open water swells exceeding >3m (>10ft) only occur 1.4% of the time in a typical northern hemisphere autumn, 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 ratio of these swells that coincided with expected offshore winds, and given the fact that Cliff Beach (Lewis) is exposed to open water swells, we estimate that clean surf can be found at Cliff Beach (Lewis) about 26% of the time and that surf is blown out by onshore wind 55% of the time. This is means that we expect 74 days with waves in a typical northern hemisphere autumn, of which 24 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.
