Cremorne Point Surf Stats

The figure shows the combination of swells directed at Cremorne Point over a normal June and is based upon 2786 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coast so we have chosen the best grid node based on what we know about Cremorne Point. In the case of Cremorne Point, the best grid node is 60 km away (37 miles). The rose diagram illustrates the distribution of swell sizes and swell direction, while the graph at the bottom shows the same thing without direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These happened only 17% of the time. Green and yellow represent increasing swell sizes and red shows the biggest 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 prevailing swell direction, shown by the longest spokes, was SSW, whereas the the prevailing wind blows from the WNW. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Cremorne Point and offshore. We group these with the no surf category of the bar chart. To simplify things we don't show these in the rose graph. Because wind determines whether or not waves are good for surfing at Cremorne Point, you can load a different image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical June, swells large enough to cause clean enough to surf waves at Cremorne Point run for about 13% of the time.
