Cliff Beach (Lewis) Swell Statistics, December: 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 December and is based upon 2705 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 biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies 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 7 days. Open water swells exceeding >3m (>10ft) only happen 3% of the time in a typical December, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Cliff Beach (Lewis) is exposed to open water swells, we think that that clean surf can be found at Cliff Beach (Lewis) about 23% of the time and that surf is spoilt by onshore wind 61% of the time. This is means that we expect 25 days with waves in a typical December, of which 7 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.
