Ann Street Peaks Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Ann Street Peaks 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 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 largest 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 most common swell direction, shown by the longest spokes, was ESE, whereas the the most common 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 28% of the time, equivalent to 25 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere winter but 2% of the time we expect swell in the range 2-3m (6.5-10ft) 2%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Ann Street Peaks is exposed to open water swells, we think that that clean surf can be found at Ann Street Peaks about 28% of the time and that surf is messed up by onshore wind 53% of the time. This is means that we expect 74 days with waves in a typical southern hemisphere winter, of which 25 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.
