Statistiques de Houle pour Dinas Dinlle, Décembre: Toutes Houles – Tous Vents

The graph shows the variation of swells directed at Dinas Dinlle over a normal December. It is based on 2705 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coastline so we have chosen the best grid node based on what we know about Dinas Dinlle. In the case of Dinas Dinlle, the best grid node is 14 km away (9 miles).

The rose diagram describes the distribution of swell sizes and swell direction, while the graph at the bottom shows the same thing but lacks direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These happened 38% of the time. Green and yellow represent increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was SW (which was the same as the prevailing wind direction). Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Dinas Dinlle and offshore. We group these with the no surf category of the bar chart. To keep it simple we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Dinas Dinlle, you can load a different image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical December, swells large enough to cause good for surfing waves at Dinas Dinlle run for about 33% of the time.

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.
