Garths Reef Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Garths Reef that coincided with light winds or offshore conditions through a typical October and is based upon 2480 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 red shows highest 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 WNW, whereas the the dominant wind blows from the N. 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 38% of the time, equivalent to 12 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Garths Reef is quite sheltered from open water swells, we estimate that clean surf can be found at Garths Reef about 38% of the time and that surf is messed up by onshore wind 20% of the time. This is means that we expect 18 days with waves in a typical October, of which 12 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.
