Good Surf

(light / offshore wind)

The figure shows the combination of swells directed at Margaret River Bommie over a normal December and is based upon 3448 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind and surf right at the coast so we have chosen the best grid node based on what we know about Margaret River Bommie. In this particular case the best grid node is 45 km away (28 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 illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These were forecast only 0.5% of the time. Green and yellow represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell occurs. The diagram implies that the prevailing swell direction, shown by the biggest spokes, was SW, whereas the the prevailing wind blows from the SSE. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Margaret River Bommie and out to sea. We lump these in with the no surf category of the bar chart. To avoid confusion we don't show these in the rose diagram. Because wind determines whether or not waves are clean enough to surf at Margaret River Bommie, you can select a similar diagram that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical December, swells large enough to cause surfable waves at Margaret River Bommie run for about 100% of the time.
