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 through a typical northern hemisphere spring. It is based on 8682 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 commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the largest spokes, was NW, 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 24% of the time, equivalent to 22 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (5 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Lackan Bay is slightly protected from open water swells, we think that that clean surf can be found at Lackan Bay about 24% of the time and that surf is spoilt by onshore wind 25% of the time. This is means that we expect 45 days with waves in a typical northern hemisphere spring, of which 22 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.
