Express Point Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Express Point that coincided with light winds or offshore conditions over a normal southern hemisphere autumn. It is based on 8052 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 represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SW, whereas the the prevailing 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 18% of the time, equivalent to 16 days. Open water swells exceeding >3m (>10ft) only happen 0.7% of the time in a typical southern hemisphere autumn, equivalent to just one day but 5% of the time we expect swell in the range 2-3m (6.5-10ft) 5%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Express Point is slightly protected from open water swells, we calculate that clean surf can be found at Express Point about 18% of the time and that surf is messed up by onshore wind 26% of the time. This is means that we expect 40 days with waves in a typical southern hemisphere autumn, of which 16 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.
