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

The rose diagram shows only the swells directed at Dinas Dinlle that coincided with light winds or offshore conditions through a typical November and is based upon 2866 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 illustrate increasing swell sizes and red shows largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was SW, whereas the the most common wind blows from the W. 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 0.3% of the time, equivalent to 0 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 forecast offshore winds, and given the fact that Dinas Dinlle is slightly protected from open water swells, we calculate that clean surf can be found at Dinas Dinlle about 0.3% of the time and that surf is messed up by onshore wind 23% of the time. This is means that we expect 7 days with waves in a typical November, of which 0 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
