Warriewood Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Warriewood that coincided with light winds or offshore conditions through a typical southern hemisphere spring. It is based on 8476 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 illustrate increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In either 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 ESE, whereas the the dominant wind blows from the ENE. 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 28% of the time, equivalent to 25 days. Open water swells exceeding >3m (>10ft) only arise 1.2% of the time in a typical southern hemisphere spring, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Warriewood is exposed to open water swells, we estimate that clean surf can be found at Warriewood about 28% of the time and that surf is messed up by onshore wind 54% of the time. This is means that we expect 75 days with waves in a typical southern hemisphere spring, of which 25 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.
