Wainui Reef Swell Statistics, May: Surf with Light or Offshore Winds

This image shows only the swells directed at Wainui Reef that coincided with light winds or offshore conditions through a typical May and is based upon 2838 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 represent increasing swell sizes and red shows highest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the biggest 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 29% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Wainui Reef is slightly protected from open water swells, we think that that clean surf can be found at Wainui Reef about 29% of the time and that surf is spoilt by onshore wind 22% of the time. This is means that we expect 16 days with waves in a typical May, of which 9 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.
