Clarence River Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Clarence River that coincided with light winds or offshore conditions through a typical year. It is based on 33212 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and largest 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 dominant swell direction, shown by the longest spokes, was SE, whereas the the most common wind blows from the NNW. 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 36% of the time, equivalent to 131 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (7 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Clarence River is exposed to open water swells, we think that that clean surf can be found at Clarence River about 36% of the time and that surf is messed up by onshore wind 36% of the time. This is means that we expect 263 days with waves in a typical year, of which 131 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.
