Clarence River Swell Statistics, June: 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 June and is based upon 2306 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 illustrate increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SE, whereas the the dominant wind blows from the W. 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 48% of the time, equivalent to 14 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Clarence River is exposed to open water swells, we estimate that clean surf can be found at Clarence River about 48% of the time and that surf is spoilt by onshore wind 30% of the time. This is means that we expect 23 days with waves in a typical June, of which 14 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.
