Ballina South Wall Swell Statistics, Novembre: All Swell – Any Wind

The rose diagram illustrates the variation of swells directed at Ballina South Wall over a normal November, based on 2867 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind and surf right at the shore so we have chosen the most applicable grid node based on what we know about Ballina South Wall. In the case of Ballina South Wall, the best grid node is 43 km away (27 miles).

The rose diagram shows the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing but without direction information. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These were forecast only 43% of the time. Green and yellow illustrate increasing swell sizes and red represents largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was ENE, whereas the the most common wind blows from the NE. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Ballina South Wall and offshore. We combine these with the no surf category of the bar chart. To keep it simple we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Ballina South Wall, you can view an alternative image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical November, swells large enough to cause good for surfing waves at Ballina South Wall run for about 57% of the time.

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.
