Ulladulla Bommie Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Ulladulla Bommie that coincided with light winds or offshore conditions through a typical southern hemisphere summer. It is based on 8485 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 illustrate increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the biggest spokes, was SE, whereas the the dominant 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 13% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal southern hemisphere summer but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Ulladulla Bommie is exposed to open water swells, we calculate that clean surf can be found at Ulladulla Bommie about 13% of the time and that surf is messed up by onshore wind 54% of the time. This is means that we expect 61 days with waves in a typical southern hemisphere summer, of which 12 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.
