Lackan Bay Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Lackan Bay that coincided with light winds or offshore conditions through a typical December. It is based on 2953 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 biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the longest 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 35% of the time, equivalent to 10 days. Expect open water swells to exceed >3m (>10ft) 20% of the time (6 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Lackan Bay is slightly protected from open water swells, we estimate that clean surf can be found at Lackan Bay about 35% of the time and that surf is messed up by onshore wind 25% of the time. This is means that we expect 18 days with waves in a typical December, of which 10 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.
