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

The rose diagram shows only the swells directed at Dongara-Port Denison that coincided with light winds or offshore conditions through a typical southern hemisphere summer. It is based on 8485 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the longest 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 19% of the time, equivalent to 17 days. Open water swells exceeding >3m (>10ft) only happen 1.4% of the time in a typical southern hemisphere summer, equivalent to just one day but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Dongara-Port Denison is exposed to open water swells, we think that that clean surf can be found at Dongara-Port Denison about 19% of the time and that surf is messed up by onshore wind 67% of the time. This is means that we expect 78 days with waves in a typical southern hemisphere summer, of which 17 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.
