Bay of Skaill Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Bay of Skaill that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 6580 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 illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies 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 31% of the time, equivalent to 28 days. Open water swells exceeding >3m (>10ft) only arise 1.6% of the time in a typical northern hemisphere spring, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Bay of Skaill is exposed to open water swells, we think that that clean surf can be found at Bay of Skaill about 31% of the time and that surf is spoilt by onshore wind 47% of the time. This is means that we expect 71 days with waves in a typical northern hemisphere spring, of which 28 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.
