Wainui Reef Swell Statistics, July: 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 July. It is based on 2976 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 shows largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the largest spokes, was W, whereas the the most common 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 27% of the time, equivalent to 8 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical July, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Wainui Reef is slightly protected from open water swells, we estimate that clean surf can be found at Wainui Reef about 27% of the time and that surf is spoilt by onshore wind 19% of the time. This is means that we expect 14 days with waves in a typical July, of which 8 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.
