Grishipoll Bay (Coll) Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Grishipoll Bay (Coll) that coincided with light winds or offshore conditions over a normal northern hemisphere spring. It is based on 8052 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 illustrate increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was W, 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 18% of the time, equivalent to 16 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere spring but 3% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 3%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Grishipoll Bay (Coll) is exposed to open water swells, we estimate that clean surf can be found at Grishipoll Bay (Coll) about 18% of the time and that surf is messed up by onshore wind 48% of the time. This is means that we expect 60 days with waves in a typical northern hemisphere spring, of which 16 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.
