City Beach Groyne Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at City Beach Groyne that coincided with light winds or offshore conditions over a normal October and is based upon 2976 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 illustrate increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was WSW, whereas the the dominant wind blows from the S. 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 28% of the time, equivalent to 9 days. Open water swells exceeding >3m (>10ft) only occur 2% of the time in a typical October, equivalent to just one day but 11% of the time we expect swell in the range 2-3m (6.5-10ft) 11%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that City Beach Groyne is slightly protected from open water swells, we calculate that clean surf can be found at City Beach Groyne about 28% of the time and that surf is spoilt by onshore wind 62% of the time. This is means that we expect 28 days with waves in a typical October, of which 9 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.
