Backyards Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Backyards that coincided with light winds or offshore conditions over a normal northern hemisphere spring and is based upon 8052 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 red represents the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was NNW, whereas the the prevailing wind blows from the ENE. 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 14% of the time, equivalent to 13 days. Open water swells exceeding >3m (>10ft) only arise 0.6% of the time in a typical northern hemisphere spring, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Backyards is exposed to open water swells, we calculate that clean surf can be found at Backyards about 14% of the time and that surf is messed up by onshore wind 38% of the time. This is means that we expect 47 days with waves in a typical northern hemisphere spring, of which 13 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.
