Statistiques de Houle pour Jap Rock, Automne: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Jap Rock that coincided with light winds or offshore conditions over a normal northern hemisphere autumn and is based upon 8724 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 represent increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was ENE, whereas the the most common wind blows from the E. 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 12% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere autumn. Taking into account the proportion of these swells that coincided with predicted offshore winds we calculate that clean surf can be found at Jap Rock about 12% of the time and that surf is blown out by onshore wind 47% of the time. This is means that we expect 54 days with waves in a typical northern hemisphere autumn, 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.
