Winchesteer Bay/Umpqua Jetty Swell Statistics, January: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Winchesteer Bay/Umpqua Jetty that coincided with light winds or offshore conditions over a normal January. It is based on 2620 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, 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 largest spokes, was W, whereas the the most common wind blows from the SE. 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 43% of the time, equivalent to 13 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Winchesteer Bay/Umpqua Jetty is exposed to open water swells, we calculate that clean surf can be found at Winchesteer Bay/Umpqua Jetty about 43% of the time and that surf is messed up by onshore wind 56% of the time. This is means that we expect 31 days with waves in a typical January, of which 13 days should be surfable.

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.
