Back Beach Swell Statistics, Winter: 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 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 represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SW, whereas the the most common wind blows from the E. 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 40% of the time, equivalent to 36 days. Expect open water swells to exceed >3m (>10ft) 9% of the time (8 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Back Beach is exposed to open water swells, we estimate that clean surf can be found at Back Beach about 40% of the time and that surf is spoilt by onshore wind 59% of the time. This is means that we expect 90 days with waves in a typical southern hemisphere winter, of which 36 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
