Estadísticas de Olas para Xiyong Bay, Todo el Año: Todo Oleaje – Todo Viento

The rose diagram describes the combination of swells directed at Xiyong Bay through a typical year and is based upon 34626 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the coast so we have chosen the most applicable grid node based on what we know about Xiyong Bay. In the case of Xiyong Bay, the best grid node is 5 km away (3 miles).

The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing without direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These occurred 44% of the time. Green and yellow illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was SE, whereas the the dominant wind blows from the E. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Xiyong Bay and away from the coast. We combine these with the no surf category of the bar chart. To keep it simple we don't show these in the rose diagram. Because wind determines whether or not waves are good for surfing at Xiyong Bay, you can load a different image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. Over an average year, swells large enough to cause clean enough to surf waves at Xiyong Bay run for about 56% 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.
