Whangaehu River Mouth Swell Statistics, Summer: 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 over a normal southern hemisphere summer and is based upon 8484 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 represent increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In both graphs, 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 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 0.8% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere summer. Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Whangaehu River Mouth is slightly protected from open water swells, we calculate that clean surf can be found at Whangaehu River Mouth about 0.8% of the time and that surf is messed up by onshore wind 24% of the time. This is means that we expect 23 days with waves in a typical southern hemisphere summer, of which 1 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.
