Wujiao Bay (Dongshan Dao) Surf Stats

The rose diagram describes the combination of swells directed at Wujiao Bay (Dongshan Dao) through an average October and is based upon 3471 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind and surf right at the coast so we have chosen the most applicable grid node based on what we know about Wujiao Bay (Dongshan Dao). In the case of Wujiao Bay (Dongshan Dao), the best grid node is 16 km away (10 miles). The rose diagram describes the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing but lacks direction information. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These were forecast only 11% of the time. Green and yellow illustrate increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell was forecast. The diagram implies that the dominant swell direction, shown by the longest spokes, was E, whereas the the dominant wind blows from the NE. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Wujiao Bay (Dongshan Dao) and away from the coast. We combine these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose graph. Because wind determines whether or not waves are clean enough to surf at Wujiao Bay (Dongshan Dao), you can select a similar diagram that shows only the swells that were expected to coincide with glassy or offshore wind conditions. In a typical October, swells large enough to cause surfable waves at Wujiao Bay (Dongshan Dao) run for about 89% of the time.
