Joss Bay Swell Statistics, February: Surf with Light or Offshore Winds

This image shows only the swells directed at Joss Bay that coincided with light winds or offshore conditions over a normal February and is based upon 2435 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 biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was N, whereas the the prevailing wind blows from the SW. 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 0.6% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal February. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Joss Bay is slightly protected from open water swells, we calculate that clean surf can be found at Joss Bay about 0.6% of the time and that surf is spoilt by onshore wind 9% of the time. This is means that we expect 3 days with waves in a typical February, of which 0 days should be clean enough to surf.

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.
