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

This image shows only the swells directed at Whangaehu River Mouth that coincided with light winds or offshore conditions through a typical southern hemisphere autumn. It is based on 8051 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 show increasing swell sizes and largest 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 was forecast.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was W, 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 0.9% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere autumn. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Whangaehu River Mouth is slightly protected from open water swells, we estimate that clean surf can be found at Whangaehu River Mouth about 0.9% of the time and that surf is messed up by onshore wind 23% of the time. This is means that we expect 22 days with waves in a typical southern hemisphere autumn, of which 1 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.
