Ranganunu Harbour Swell Statistics, Ottobre: Surf with Light or Offshore Winds

This image shows only the swells directed at Ranganunu Harbour that coincided with light winds or offshore conditions through a typical October. It is based on 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 biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was ENE, whereas the the prevailing wind blows from the WSW. 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 5% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal October. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Ranganunu Harbour is slightly protected from open water swells, we calculate that clean surf can be found at Ranganunu Harbour about 5% of the time and that surf is messed up by onshore wind 10% of the time. This is means that we expect 5 days with waves in a typical October, of which 2 days should be clean enough to surf.

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.
