Apua Point Swell Statistics, Febbraio: Surf with Light or Offshore Winds
This image shows only the swells directed at Apua Point that coincided with light winds or offshore conditions over a normal February. It is based on 2102 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 highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast.
The diagram indicates that the dominant swell direction, shown by the longest spokes, was SE, whereas the the dominant wind blows from the ENE. 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 5% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal February. Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Apua Point is exposed to open water swells, we estimate that clean surf can be found at Apua Point about 5% of the time and that surf is blown out by onshore wind 35% of the time. This is means that we expect 11 days with waves in a typical February, of which 1 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.
