Whangaehu River Mouth Swell Statistics, November: 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 November and is based upon 2867 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 red represents the biggest 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 dominant swell direction, shown by the largest spokes, was W, whereas the the prevailing wind blows from the WNW. 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 1.0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November. Taking into account the ratio of these swells that coincided with expected 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 1.0% of the time and that surf is spoilt by onshore wind 37% of the time. This is means that we expect 11 days with waves in a typical November, of which 0 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.
