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

This image shows only the swells directed at Barvas (Lewis) that coincided with light winds or offshore conditions over a normal March. It is based on 2964 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 red illustrates the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the largest spokes, was NW, 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 20% of the time, equivalent to 6 days. Open water swells exceeding >3m (>10ft) only happen 1.8% of the time in a typical March, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Barvas (Lewis) is exposed to open water swells, we calculate that clean surf can be found at Barvas (Lewis) about 20% of the time and that surf is blown out by onshore wind 65% of the time. This is means that we expect 26 days with waves in a typical March, of which 6 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.
