North Myrtle/27th Avenue South Swell Statistics, September: Surf with Light or Offshore Winds

This image shows only the swells directed at North Myrtle/27th Avenue South 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and red shows highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was SE, whereas the the dominant 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 31% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal September. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that North Myrtle/27th Avenue South is exposed to open water swells, we estimate that clean surf can be found at North Myrtle/27th Avenue South about 31% of the time and that surf is messed up by onshore wind 43% of the time. This is means that we expect 22 days with waves in a typical September, 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.
