Statistiques de Houle pour Diamond Street, Toute l'Année: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Diamond Street that coincided with light winds or offshore conditions over a normal year. It is based on 34628 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red shows highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WSW, whereas the the dominant wind blows from the W. 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 25% of the time, equivalent to 91 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal year but 4% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 4%, equivalent to (15 days). Taking into account the proportion of these swells that coincided with expected offshore winds we estimate that clean surf can be found at Diamond Street about 25% of the time and that surf is blown out by onshore wind 23% of the time. This is means that we expect 175 days with waves in a typical year, of which 91 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.
