Statistiques de Houle pour Diamond Head, Octobre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Diamond Head that coincided with light winds or offshore conditions through a typical October and is based upon 2976 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 represent increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the largest spokes, was E, whereas the the prevailing wind blows from the NE. 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 13% of the time, equivalent to 4 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal October. Taking into account the fraction of these swells that coincided with predicted offshore winds we calculate that clean surf can be found at Diamond Head about 13% of the time and that surf is spoilt by onshore wind 34% of the time. This is means that we expect 15 days with waves in a typical October, of which 4 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.
