Statistiques de Houle pour Diamond Street, Septembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Diamond Street that coincided with light winds or offshore conditions through a typical September. It is based on 2880 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 represent increasing swell sizes and red illustrates the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the longest spokes, was WSW, whereas the the most common 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 15% of the time, equivalent to 4 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal September. Taking into account the proportion of these swells that coincided with forecast offshore winds we estimate that clean surf can be found at Diamond Street about 15% of the time and that surf is messed up by onshore wind 15% of the time. This is means that we expect 9 days with waves in a typical September, of which 4 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.
