Back Strands Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Back Strands that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 6931 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 illustrates the highest swells, greater than >3m (>10ft). In each graph, 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 biggest spokes, was W, 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 31% of the time, equivalent to 28 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (5 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Back Strands is slightly protected from open water swells, we estimate that clean surf can be found at Back Strands about 31% of the time and that surf is spoilt by onshore wind 56% of the time. This is means that we expect 79 days with waves in a typical northern hemisphere winter, of which 28 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.
