Eoropie (Lewis) Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Eoropie (Lewis) that coincided with light winds or offshore conditions over a normal northern hemisphere summer. It is based on 8738 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 represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the prevailing 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 20% of the time, equivalent to 18 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer but 1.8% of the time we expect swell in the range 2-3m (6.5-10ft) 1.8%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Eoropie (Lewis) is exposed to open water swells, we calculate that clean surf can be found at Eoropie (Lewis) about 20% of the time and that surf is blown out by onshore wind 45% of the time. This is means that we expect 59 days with waves in a typical northern hemisphere summer, of which 18 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.
