Annascaul Rivermouth Swell Statistics, All Year: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Annascaul Rivermouth that coincided with light winds or offshore conditions through a typical year. It is based on 33204 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 show increasing swell sizes and red shows biggest 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 most common swell direction, shown by the biggest spokes, was WSW (which was the same as the prevailing wind direction). 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 4% of the time, equivalent to 15 days. Expect open water swells to exceed >3m (>10ft) 0.7% of the time (3 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Annascaul Rivermouth is quite sheltered from open water swells, we calculate that clean surf can be found at Annascaul Rivermouth about 4% of the time and that surf is messed up by onshore wind 38% of the time. This is means that we expect 153 days with waves in a typical year, of which 15 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.
