Statistiques de Houle pour North Haven, Automne: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at North Haven that coincided with light winds or offshore conditions over a normal southern hemisphere autumn. It is based on 6580 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 largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was SE, whereas the the most common 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 52% of the time, equivalent to 47 days. Open water swells exceeding >3m (>10ft) only occur 1.5% of the time in a typical southern hemisphere autumn, equivalent to just one day but 17% of the time we expect swell in the range 2-3m (6.5-10ft) 17%, equivalent to (15 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that North Haven is exposed to open water swells, we think that that clean surf can be found at North Haven about 52% of the time and that surf is blown out by onshore wind 37% of the time. This is means that we expect 81 days with waves in a typical southern hemisphere autumn, of which 47 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.
