Ansteys Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Ansteys that coincided with light winds or offshore conditions through a typical southern hemisphere winter. It is based on 8738 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 show 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 frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was E, whereas the the prevailing wind blows from the NW. 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 21% of the time, equivalent to 19 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere winter but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Ansteys is exposed to open water swells, we think that that clean surf can be found at Ansteys about 21% of the time and that surf is spoilt by onshore wind 26% of the time. This is means that we expect 43 days with waves in a typical southern hemisphere winter, of which 19 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.
