Bobby's Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Bobby's that coincided with light winds or offshore conditions through a typical December and is based upon 2953 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 largest swells greater than >3m (>10ft). 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 WNW, whereas the the most common 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 36% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal December but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with forecast offshore winds we estimate that clean surf can be found at Bobby's about 36% of the time and that surf is messed up by onshore wind 55% of the time. This is means that we expect 27 days with waves in a typical December, 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.
