Whangaehu River Mouth Swell Statistics, September: 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 September. It is based on 2879 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 the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was W, whereas the the prevailing 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal September. Taking into account the ratio 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 3% of the time and that surf is messed up by onshore wind 36% of the time. This is means that we expect 12 days with waves in a typical September, 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.
