Cliad Bay (Coll) Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Cliad Bay (Coll) that coincided with light winds or offshore conditions through a typical northern hemisphere summer. It is based on 8738 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 biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was W, whereas the the prevailing 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 13% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere summer. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Cliad Bay (Coll) is exposed to open water swells, we think that that clean surf can be found at Cliad Bay (Coll) about 13% of the time and that surf is spoilt by onshore wind 46% of the time. This is means that we expect 54 days with waves in a typical northern hemisphere summer, of which 12 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.
