Statistiques de Houle pour North Haven, Printemps: 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 spring. It is based on 7252 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 red illustrates biggest swells greater than >3m (>10ft). In both graphs, 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 biggest spokes, was SE, whereas the the prevailing wind blows from the ENE. 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 31% of the time, equivalent to 28 days. Open water swells exceeding >3m (>10ft) only arise 1.1% of the time in a typical southern hemisphere spring, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the proportion of these swells that coincided with predicted 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 31% of the time and that surf is blown out by onshore wind 51% of the time. This is means that we expect 75 days with waves in a typical southern hemisphere spring, of which 28 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.
