Back Beach Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Back Beach that coincided with light winds or offshore conditions through a typical southern hemisphere spring and is based upon 7252 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 represents the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SW, whereas the the dominant wind blows from the S. 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 16% of the time, equivalent to 15 days. Expect open water swells to exceed >3m (>10ft) 3% of the time (3 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Back Beach is exposed to open water swells, we calculate that clean surf can be found at Back Beach about 16% of the time and that surf is blown out by onshore wind 84% of the time. This is means that we expect 91 days with waves in a typical southern hemisphere spring, of which 15 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.
