Statistiques de Houle pour Yasuda Rivermouth, Automne: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Yasuda Rivermouth that coincided with light winds or offshore conditions over a normal northern hemisphere autumn and is based upon 7252 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 represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the largest spokes, was SSE, whereas the the prevailing wind blows from the N. 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 19% of the time, equivalent to 17 days. Open water swells exceeding >3m (>10ft) only happen 1.6% of the time in a typical northern hemisphere autumn, equivalent to just one day but 5% of the time we expect swell in the range 2-3m (6.5-10ft) 5%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Yasuda Rivermouth is exposed to open water swells, we estimate that clean surf can be found at Yasuda Rivermouth about 19% of the time and that surf is spoilt by onshore wind 11% of the time. This is means that we expect 27 days with waves in a typical northern hemisphere autumn, of which 17 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.
