Statistiques de Houle pour Jap Rock, Juillet: 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 July and is based upon 2480 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was ENE, whereas the the most common wind blows from the SSE. 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 5% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal July. Taking into account the ratio of these swells that coincided with expected offshore winds we estimate that clean surf can be found at Jap Rock about 5% of the time and that surf is blown out by onshore wind 32% of the time. This is means that we expect 11 days with waves in a typical July, of which 2 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.
