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

This image shows only the swells directed at Downtowns that coincided with light winds or offshore conditions over a normal September and is based upon 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 illustrate increasing swell sizes and red shows largest 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 prevailing swell direction, shown by the largest spokes, was SW, whereas the the most common wind blows from the SE. 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 84% of the time, equivalent to 25 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal September but 41% of the time we expect swell in the range 2-3m (6.5-10ft) 41%, equivalent to (12 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Downtowns is slightly protected from open water swells, we estimate that clean surf can be found at Downtowns about 84% of the time and that surf is blown out by onshore wind 14% of the time. This is means that we expect 29 days with waves in a typical September, of which 25 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.
