Grandview Swell Statistics, Setembro: Surf with Light or Offshore Winds

This image shows only the swells directed at Grandview that coincided with light winds or offshore conditions over a normal September. It is based on 2880 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 represent increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was ESE, whereas the the prevailing 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 27% of the time, equivalent to 8 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the fraction of these swells that coincided with expected offshore winds we estimate that clean surf can be found at Grandview about 27% of the time and that surf is messed up by onshore wind 60% of the time. This is means that we expect 26 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.
