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

This image shows only the swells directed at Back Strands that coincided with light winds or offshore conditions through a typical northern hemisphere spring and is based upon 6580 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 show increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies 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 20% of the time, equivalent to 18 days. Open water swells exceeding >3m (>10ft) only arise 1.1% of the time in a typical northern hemisphere spring, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (7 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Back Strands is slightly protected from open water swells, we think that that clean surf can be found at Back Strands about 20% of the time and that surf is spoilt by onshore wind 47% of the time. This is means that we expect 61 days with waves in a typical northern hemisphere spring, 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.
