Jenness Beach Swell Statistics, August: 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 August and is based upon 2975 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 the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was ESE, whereas the the prevailing 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 36% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal August. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Jenness Beach is exposed to open water swells, we calculate that clean surf can be found at Jenness Beach about 36% of the time and that surf is blown out by onshore wind 37% of the time. This is means that we expect 23 days with waves in a typical August, 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.
