Wainakarua River Mouth Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Wainakarua River Mouth that coincided with light winds or offshore conditions over a normal southern hemisphere autumn. It is based on 8682 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 illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SSE, whereas the the dominant wind blows from the NW. 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 37% of the time, equivalent to 34 days. Expect open water swells to exceed >3m (>10ft) 1.7% of the time (2 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Wainakarua River Mouth is exposed to open water swells, we estimate that clean surf can be found at Wainakarua River Mouth about 37% of the time and that surf is spoilt by onshore wind 34% of the time. This is means that we expect 65 days with waves in a typical southern hemisphere autumn, of which 34 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.
