Statistiques de Houle pour Dump Beach, Août: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dump Beach that coincided with light winds or offshore conditions through a typical August. It is based on 2976 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 biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was SSW, whereas the the prevailing wind blows from the WNW. 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 34% of the time, equivalent to 11 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical August, equivalent to just one day but 17% of the time we expect swell in the range 2-3m (6.5-10ft) 17%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Dump Beach is slightly protected from open water swells, we calculate that clean surf can be found at Dump Beach about 34% of the time and that surf is messed up by onshore wind 39% of the time. This is means that we expect 23 days with waves in a typical August, of which 11 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.
