Statistiques de Houle pour Takara, Novembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Takara that coincided with light winds or offshore conditions through a typical November. It is based on 2867 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 show increasing swell sizes and red illustrates biggest 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 prevailing swell direction, shown by the biggest spokes, was ESE (which was the same as the prevailing wind direction). 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November. Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Takara is slightly protected from open water swells, we estimate that clean surf can be found at Takara about 4% of the time and that surf is spoilt by onshore wind 58% of the time. This is means that we expect 19 days with waves in a typical November, 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.
