Barvas (Lewis) Swell Statistics, Gennaio: Surf with Light or Offshore Winds

This image shows only the swells directed at Barvas (Lewis) that coincided with light winds or offshore conditions through a typical January. It is based on 2372 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 largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the longest spokes, was WNW, 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 7 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical January, 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 Barvas (Lewis) is exposed to open water swells, we estimate that clean surf can be found at Barvas (Lewis) about 23% of the time and that surf is spoilt by onshore wind 64% of the time. This is means that we expect 27 days with waves in a typical January, of which 7 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.
