Zenith Beach Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Zenith Beach that coincided with light winds or offshore conditions through a typical southern hemisphere winter. It is based on 7266 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 highest 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 happens.

The diagram suggests that the most common swell direction, shown by the longest spokes, was SE, whereas the the dominant 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 45% of the time, equivalent to 41 days. Open water swells exceeding >3m (>10ft) only arise 1.3% of the time in a typical southern hemisphere winter, equivalent to just one day but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Zenith Beach is exposed to open water swells, we estimate that clean surf can be found at Zenith Beach about 45% of the time and that surf is messed up by onshore wind 35% of the time. This is means that we expect 73 days with waves in a typical southern hemisphere winter, of which 41 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.
