Avalon Point Swell Statistics, December: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Avalon Point that coincided with light winds or offshore conditions through a typical December. It is based on 2953 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the longest spokes, was WSW, whereas the the prevailing wind blows from the SSE. 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 28% of the time, equivalent to 8 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal December but 6% of the time we expect swell in the range 2-3m (6.5-10ft) 6%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Avalon Point is slightly protected from open water swells, we estimate that clean surf can be found at Avalon Point about 28% of the time and that surf is blown out by onshore wind 35% of the time. This is means that we expect 19 days with waves in a typical December, of which 8 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.
