Cannibal Bay Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Cannibal Bay that coincided with light winds or offshore conditions through a typical southern hemisphere autumn. It is based on 8052 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 red shows largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was S, whereas the the most common wind blows from the WNW. 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 33 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere autumn but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Cannibal Bay is exposed to open water swells, we calculate that clean surf can be found at Cannibal Bay about 36% of the time and that surf is messed up by onshore wind 36% of the time. This is means that we expect 66 days with waves in a typical southern hemisphere autumn, of which 33 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.
