Awakino River Mouth Swell Statistics, All Year: Surf with Light or Offshore Winds
The rose diagram shows only the swells directed at Awakino River Mouth that coincided with light winds or offshore conditions through a typical year and is based upon 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.
The diagram implies that the most common swell direction, shown by the largest spokes, was WSW (which was the same as the dominant wind direction). 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 5% of the time, equivalent to 18 days. Open water swells exceeding >3m (>10ft) only happen 0.3% of the time in a typical year, equivalent to just one day but 5% of the time we expect swell in the range 2-3m (6.5-10ft) 5%, equivalent to (18 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Awakino River Mouth is quite sheltered from open water swells, we think that that clean surf can be found at Awakino River Mouth about 5% of the time and that surf is blown out by onshore wind 27% of the time. This is means that we expect 117 days with waves in a typical year, of which 18 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.
