Waipio Bay Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Waipio Bay that coincided with light winds or offshore conditions over a normal October and is based upon 2976 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 illustrate increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was NNE, whereas the the prevailing wind blows from the E. 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 1.3% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal October. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Waipio Bay is exposed to open water swells, we estimate that clean surf can be found at Waipio Bay about 1.3% of the time and that surf is blown out by onshore wind 59% of the time. This is means that we expect 19 days with waves in a typical October, 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.
