Sapphire Street Swell Statistics, October: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Sapphire Street that coincided with light winds or offshore conditions through a typical October and is based upon 2976 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 largest swells, greater than >3m (>10ft). In both graphs, 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 SW, whereas the the most common wind blows from the W. 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 43% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal October. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Sapphire Street is exposed to open water swells, we estimate that clean surf can be found at Sapphire Street about 43% of the time and that surf is spoilt by onshore wind 52% of the time. This is means that we expect 29 days with waves in a typical October, of which 13 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.
