Statistiques de Houle pour North Jetty, Juillet: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at North Jetty that coincided with light winds or offshore conditions through a typical July. It is based on 2480 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 shows biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the largest spokes, was E, whereas the the prevailing wind blows from the S. 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 1.8% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal July. Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that North Jetty is exposed to open water swells, we calculate that clean surf can be found at North Jetty about 1.8% of the time and that surf is spoilt by onshore wind 8% of the time. This is means that we expect 3 days with waves in a typical July, of which 1 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.
