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

The rose diagram shows only the swells directed at Lackan Bay that coincided with light winds or offshore conditions through a typical December. It is based on 2705 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 highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the largest spokes, was WNW, 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 34% of the time, equivalent to 10 days. Expect open water swells to exceed >3m (>10ft) 21% of the time (6 days). Taking into account the proportion of these swells that coincided with forecast 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 34% of the time and that surf is blown out 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 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.
