Winchesteer Bay/Umpqua Jetty Swell Statistics, All Year: All Swell – Any Wind

This picture illustrates the range of swells directed at Winchesteer Bay/Umpqua Jetty over a normal year. It is based on 33260 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coast so we have chosen the most applicable grid node based on what we know about Winchesteer Bay/Umpqua Jetty. In the case of Winchesteer Bay/Umpqua Jetty, the best grid node is 30 km away (19 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 represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These happened only 7% of the time. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was W, whereas the the most common wind blows from the NW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Winchesteer Bay/Umpqua Jetty and out to sea. We group these with the no surf category of the bar chart. To simplify things we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Winchesteer Bay/Umpqua Jetty, you can view an alternative image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. During a typical year, swells large enough to cause good for surfing waves at Winchesteer Bay/Umpqua Jetty run for about 93% 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.
