Colac Bay Swell Statistics, Ottobre: Surf with Light or Offshore Winds

This image shows only the swells directed at Colac Bay 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 represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and red illustrates 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 dominant swell direction, shown by the longest spokes, was SW, whereas the the prevailing wind blows from the W. 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 17% of the time, equivalent to 5 days. Open water swells exceeding >3m (>10ft) only arise 2% of the time in a typical October, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Colac Bay is exposed to open water swells, we calculate that clean surf can be found at Colac Bay about 17% of the time and that surf is messed up by onshore wind 13% of the time. This is means that we expect 9 days with waves in a typical October, of which 5 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.
