Statistiques de Houle pour Dumps, Hiver: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dumps that coincided with light winds or offshore conditions over a normal northern hemisphere winter. 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 highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the ENE. 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 15 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere winter. Taking into account the fraction of these swells that coincided with forecast offshore winds we calculate that clean surf can be found at Dumps about 16% of the time and that surf is messed up by onshore wind 4% of the time. This is means that we expect 18 days with waves in a typical northern hemisphere winter, of which 15 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.
