Ardnave Point and Bay (Islay) Swell Statistics, Dicembre: Surf with Light or Offshore Winds

This image shows only the swells directed at Ardnave Point and Bay (Islay) that coincided with light winds or offshore conditions over a normal 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 represent increasing swell sizes and red shows highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the biggest spokes, was W, whereas the the dominant 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 30% of the time, equivalent to 9 days. Expect open water swells to exceed >3m (>10ft) 13% of the time (4 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Ardnave Point and Bay (Islay) is quite sheltered from open water swells, we calculate that clean surf can be found at Ardnave Point and Bay (Islay) about 30% of the time and that surf is blown out by onshore wind 34% of the time. This is means that we expect 19 days with waves in a typical December, of which 9 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.
