Bay of Skaill Swell Statistics, Novembre: 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 over a normal November. It is based on 2867 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 highest swells greater than >3m (>10ft) are shown in red. 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 longest spokes, was WNW, whereas the the dominant wind blows from the WSW. 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 29% of the time, equivalent to 9 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical November, equivalent to just one day but 13% of the time we expect swell in the range 2-3m (6.5-10ft) 13%, equivalent to (4 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Bay of Skaill is exposed to open water swells, we calculate that clean surf can be found at Bay of Skaill about 29% of the time and that surf is spoilt by onshore wind 55% of the time. This is means that we expect 25 days with waves in a typical November, of which 9 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.
