Ballycotton Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at Ballycotton that coincided with light winds or offshore conditions over a normal January and is based upon 2372 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 red represents the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the longest spokes, was SW, whereas the the dominant 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 28% of the time, equivalent to 9 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Ballycotton is quite sheltered from open water swells, we calculate that clean surf can be found at Ballycotton about 28% of the time and that surf is blown out by onshore wind 13% of the time. This is means that we expect 13 days with waves in a typical January, 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.
