Motunau Beach Swell Statistics, Ottobre: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Motunau Beach that coincided with light winds or offshore conditions through a typical October. 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 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 the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was SSE, whereas the the prevailing 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 30% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal October but 10% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 10%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Motunau Beach is exposed to open water swells, we estimate that clean surf can be found at Motunau Beach about 30% of the time and that surf is blown out by onshore wind 39% of the time. This is means that we expect 21 days with waves in a typical October, of which 9 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.
