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

This image shows only the swells directed at Cathedral Rock that coincided with light winds or offshore conditions through a typical year. It is based on 34628 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 show increasing swell sizes and red illustrates 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 most common swell direction, shown by the longest spokes, was SW, whereas the the dominant 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 6% of the time, equivalent to 22 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal year but 1.3% of the time we expect swell in the range 2-3m (6.5-10ft) 1.3%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Cathedral Rock is slightly protected from open water swells, we think that that clean surf can be found at Cathedral Rock about 6% of the time and that surf is blown out by onshore wind 31% of the time. This is means that we expect 135 days with waves in a typical year, of which 22 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.
