Yaroomba Beach Surf Stats

This chart illustrates the variation of swells directed at Yaroomba Beach through an average June and is based upon 3384 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the shore so we have chosen the optimum grid node based on what we know about Yaroomba Beach. In the case of Yaroomba Beach, the best grid node is 41 km away (25 miles). The rose diagram illustrates the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing but without direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These were forecast only 12% of the time. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, 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 largest spokes, was ESE, whereas the the most common wind blows from the S. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Yaroomba Beach and offshore. We group 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 good for surfing at Yaroomba Beach, you can load a different image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. In a typical June, swells large enough to cause clean enough to surf waves at Yaroomba Beach run for about 88% of the time.
