Cathedral Rock Swell Statistics, All Year: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Cathedral Rock that coincided with light winds or offshore conditions through a typical year and is based upon 28044 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 represent increasing swell sizes and red represents the biggest 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 prevailing swell direction, shown by the biggest spokes, was SW, whereas the the prevailing wind blows from the WSW. 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 8% of the time, equivalent to 29 days. Open water swells exceeding >3m (>10ft) only happen 0.2% of the time in a typical year, equivalent to just one day but 1.6% of the time we expect swell in the range 2-3m (6.5-10ft) 1.6%, equivalent to (6 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Cathedral Rock is slightly protected from open water swells, we calculate that clean surf can be found at Cathedral Rock about 8% of the time and that surf is spoilt by onshore wind 31% of the time. This is means that we expect 142 days with waves in a typical year, of which 29 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.
