Okiwi - Whangapoua Estuary Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Okiwi - Whangapoua Estuary that coincided with light winds or offshore conditions through a typical year and is based upon 33260 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 highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the longest spokes, was ENE, whereas the the dominant wind blows from the WSW. 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 10% of the time, equivalent to 36 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal year but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Okiwi - Whangapoua Estuary is slightly protected from open water swells, we think that that clean surf can be found at Okiwi - Whangapoua Estuary about 10% of the time and that surf is blown out by onshore wind 25% of the time. This is means that we expect 128 days with waves in a typical year, of which 36 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.
