41st Ave (The Hook - Shark Cove) Surf Stats

This image shows the variation of swells directed at 41st Ave (The Hook - Shark Cove) through an average May and is based upon 3422 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind or surf right at the coastline so we have chosen the best grid node based on what we know about 41st Ave (The Hook - Shark Cove). In the case of 41st Ave (The Hook - Shark Cove), the best grid node is 48 km away (30 miles). The rose diagram describes the distribution of swell sizes and directions, while the graph at the bottom shows the same thing but lacks 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 73% of the time. Green and yellow show increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs. The diagram implies that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the prevailing wind blows from the WNW. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from 41st Ave (The Hook - Shark Cove) and away from the coast. We combine 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 surfable at 41st Ave (The Hook - Shark Cove), you can view an alternative image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. In a typical May, swells large enough to cause good for surfing waves at 41st Ave (The Hook - Shark Cove) run for about 19% of the time.
