Balephuil (Tiree) Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Balephuil (Tiree) that coincided with light winds or offshore conditions over a normal December. It is based on 2705 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 show increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the longest 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 13% of the time, equivalent to 4 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Balephuil (Tiree) is exposed to open water swells, we think that that clean surf can be found at Balephuil (Tiree) about 13% of the time and that surf is spoilt by onshore wind 71% of the time. This is means that we expect 25 days with waves in a typical December, of which 4 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.
