Ballinskelligs Bay Swell Statistics, February: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Ballinskelligs Bay that coincided with light winds or offshore conditions through a typical February. It is based on 2664 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 represent increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was WSW, 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 8% of the time, equivalent to 2 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical February, equivalent to just one day. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Ballinskelligs Bay is slightly protected from open water swells, we calculate that clean surf can be found at Ballinskelligs Bay about 8% of the time and that surf is messed up by onshore wind 36% of the time. This is means that we expect 12 days with waves in a typical February, of which 2 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.
