Avalon-North Swell Statistics, November: Surf with Light or Offshore Winds

This image shows only the swells directed at Avalon-North that coincided with light winds or offshore conditions over a normal November. It is based on 2387 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 show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was E (which was the same as the dominant wind direction). 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November. Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Avalon-North is slightly protected from open water swells, we estimate that clean surf can be found at Avalon-North about 4% of the time and that surf is blown out by onshore wind 17% of the time. This is means that we expect 6 days with waves in a typical November, of which 1 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.
