Point Ronald and Princetown Swell Statistics, September: Surf with Light or Offshore Winds

This image shows only the swells directed at Point Ronald and Princetown that coincided with light winds or offshore conditions through a typical September. It is based on 2400 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and red shows the largest 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 prevailing swell direction, shown by the longest spokes, was SW, whereas the the most common wind blows from the WNW. 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. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Point Ronald and Princetown is exposed to open water swells, we calculate that clean surf can be found at Point Ronald and Princetown about 27% of the time and that surf is spoilt by onshore wind 73% of the time. This is means that we expect 30 days with waves in a typical September, 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.
