Ballybunion Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Ballybunion that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 8724 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 represents largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was W, 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 23% of the time, equivalent to 21 days. Open water swells exceeding >3m (>10ft) only happen 0.6% of the time in a typical northern hemisphere autumn, equivalent to just one day but 6% of the time we expect swell in the range 2-3m (6.5-10ft) 6%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Ballybunion is exposed to open water swells, we estimate that clean surf can be found at Ballybunion about 23% of the time and that surf is spoilt by onshore wind 74% of the time. This is means that we expect 88 days with waves in a typical northern hemisphere autumn, of which 21 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
