Statistiques de Houle pour Yokohama Bay, Avril: 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 April. It is based on 2160 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and red represents largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the largest spokes, was NW, whereas the the most common 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 47% of the time, equivalent to 14 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal April but 16% of the time we expect swell in the range 2-3m (6.5-10ft) 16%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Yokohama Bay is exposed to open water swells, we calculate that clean surf can be found at Yokohama Bay about 47% of the time and that surf is blown out by onshore wind 4% of the time. This is means that we expect 15 days with waves in a typical April, of which 14 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.
