Statistiques de Houle pour Yokohama Bay, Février: 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 February. It is based on 2102 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and largest 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 dominant swell direction, shown by the longest 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 63% of the time, equivalent to 18 days. Open water swells exceeding >3m (>10ft) only happen 4% of the time in a typical February, equivalent to just one day but 34% of the time we expect swell in the range 2-3m (6.5-10ft) 34%, equivalent to (10 days). Taking into account the fraction of these swells that coincided with forecast 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 63% of the time and that surf is spoilt by onshore wind 18% of the time. This is means that we expect 23 days with waves in a typical February, of which 18 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.
