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

This image shows only the swells directed at Lackan Bay that coincided with light winds or offshore conditions over a normal northern hemisphere spring and is based upon 8052 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red represents largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was NW, whereas the the most common 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 25% of the time, equivalent to 23 days. Expect open water swells to exceed >3m (>10ft) 7% of the time (6 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Lackan Bay is slightly protected from open water swells, we calculate that clean surf can be found at Lackan Bay about 25% of the time and that surf is spoilt by onshore wind 24% of the time. This is means that we expect 45 days with waves in a typical northern hemisphere spring, of which 23 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.
