48th Street Swell Statistics, August: Surf with Light or Offshore Winds

This image shows only the swells directed at 48th Street that coincided with light winds or offshore conditions through a typical August and is based upon 2976 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 highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SE, whereas the the dominant wind blows from the SSW. 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 34% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal August. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that 48th Street is exposed to open water swells, we estimate that clean surf can be found at 48th Street about 34% of the time and that surf is spoilt by onshore wind 47% of the time. This is means that we expect 25 days with waves in a typical August, of which 11 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.
