Statistiques de Houle pour Dirk Hartog Island, Automne: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dirk Hartog Island that coincided with light winds or offshore conditions over a normal southern hemisphere autumn and is based upon 8052 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 biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was SW, whereas the the prevailing 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 22% of the time, equivalent to 20 days. Open water swells exceeding >3m (>10ft) only occur 1.0% of the time in a typical southern hemisphere autumn, equivalent to just one day but 13% of the time we expect swell in the range 2-3m (6.5-10ft) 13%, equivalent to (12 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Dirk Hartog Island is slightly protected from open water swells, we calculate that clean surf can be found at Dirk Hartog Island about 22% of the time and that surf is spoilt by onshore wind 76% of the time. This is means that we expect 89 days with waves in a typical southern hemisphere autumn, of which 20 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.
