Statistiques de Houle pour Doughnuts Backreef, Avril: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Doughnuts Backreef that coincided with light winds or offshore conditions over a normal April and is based upon 2640 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 represents highest swells greater than >3m (>10ft). 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 S, whereas the the dominant 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 30% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal April but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Doughnuts Backreef is exposed to open water swells, we think that that clean surf can be found at Doughnuts Backreef about 30% of the time and that surf is blown out by onshore wind 60% of the time. This is means that we expect 27 days with waves in a typical April, of which 9 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.
