Statistiques de Houle pour Dongara-Port Denison, Novembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dongara-Port Denison that coincided with light winds or offshore conditions over a normal November and is based upon 2867 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 illustrates largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was SW, whereas the the most common wind blows from the S. 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 16% of the time, equivalent to 5 days. Open water swells exceeding >3m (>10ft) only occur 1.9% of the time in a typical November, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Dongara-Port Denison is exposed to open water swells, we calculate that clean surf can be found at Dongara-Port Denison about 16% of the time and that surf is spoilt by onshore wind 77% of the time. This is means that we expect 28 days with waves in a typical November, 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.
