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

This image shows only the swells directed at Balangan that coincided with light winds or offshore conditions through a typical southern hemisphere spring and is based upon 7252 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 represents the largest 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 largest spokes, was SW, whereas the the most common wind blows from the SSE. 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 69% of the time, equivalent to 63 days. Open water swells exceeding >3m (>10ft) only happen 0.8% of the time in a typical southern hemisphere spring, equivalent to just one day but 35% of the time we expect swell in the range 2-3m (6.5-10ft) 35%, equivalent to (32 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 69% of the time and that surf is blown out by onshore wind 27% of the time. This is means that we expect 87 days with waves in a typical southern hemisphere spring, of which 63 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.
