Jenness Beach Swell Statistics, September: Surf with Light or Offshore Winds

This image shows only the swells directed at Jenness Beach that coincided with light winds or offshore conditions through a typical 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red represents highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the largest spokes, was ESE, whereas the the dominant wind blows from the SW. 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 37% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Jenness Beach is exposed to open water swells, we estimate that clean surf can be found at Jenness Beach about 37% of the time and that surf is spoilt by onshore wind 45% of the time. This is means that we expect 25 days with waves in a typical September, of which 11 days should be clean enough to surf.

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.
