Statistiques de Houle pour Yokohama Bay, Décembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Yokohama Bay that coincided with light winds or offshore conditions over a normal December and is based upon 2457 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 red represents biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the longest spokes, was NW, whereas the the prevailing wind blows from the E. 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 55% of the time, equivalent to 16 days. Open water swells exceeding >3m (>10ft) only happen 4% of the time in a typical December, equivalent to just one day but 28% of the time we expect swell in the range 2-3m (6.5-10ft) 28%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Yokohama Bay is exposed to open water swells, we estimate that clean surf can be found at Yokohama Bay about 55% of the time and that surf is blown out by onshore wind 12% of the time. This is means that we expect 20 days with waves in a typical December, of which 16 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.
