Statistiques de Houle pour Yoff Island, Mai: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Yoff Island that coincided with light winds or offshore conditions through a typical May. It is based on 2838 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 highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was NNW, whereas the the dominant wind blows from the NNW. 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 1.9% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal May. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Yoff Island is exposed to open water swells, we calculate that clean surf can be found at Yoff Island about 1.9% of the time and that surf is messed up by onshore wind 75% of the time. This is means that we expect 24 days with waves in a typical May, of which 1 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.
