Kahutara Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Kahutara that coincided with light winds or offshore conditions over a normal 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 represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the longest spokes, was SSE, 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 22% of the time, equivalent to 20 days. Open water swells exceeding >3m (>10ft) only occur 0.6% of the time in a typical southern hemisphere autumn, equivalent to just one day but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Kahutara is exposed to open water swells, we estimate that clean surf can be found at Kahutara about 22% of the time and that surf is messed up by onshore wind 46% of the time. This is means that we expect 62 days with waves in a typical southern hemisphere autumn, of which 20 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.
