Balangan Swell Statistics, September: Surf with Light or Offshore Winds

This image shows only the swells directed at Balangan that coincided with light winds or offshore conditions over a normal September and is based upon 2880 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 shows highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was SSW, whereas the the dominant wind blows from the SE. 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 97% of the time, equivalent to 29 days. Open water swells exceeding >3m (>10ft) only happen 1.8% of the time in a typical September, equivalent to just one day but 61% of the time we expect swell in the range 2-3m (6.5-10ft) 61%, equivalent to (18 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Balangan is slightly protected from open water swells, we think that that clean surf can be found at Balangan about 97% of the time and that surf is blown out by onshore wind 2.0% of the time. This is means that we expect 30 days with waves in a typical September, of which 29 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.
