Cardiff Reef Swell Statistics, Gennaio: All Swell – Any Wind

The rose diagram illustrates the variation of swells directed at Cardiff Reef through an average January and is based upon 2620 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind and surf right at the coastline so we have chosen the optimum grid node based on what we know about Cardiff Reef. In the case of Cardiff Reef, the best grid node is 19 km away (12 miles).

The rose diagram illustrates the distribution of swell sizes and directions, 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 25% of the time. Green and yellow represent increasing swell sizes and red shows the 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 most common swell direction, shown by the longest spokes, was W, whereas the the most common wind blows from the N. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Cardiff Reef and offshore. 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 clean enough to surf at Cardiff Reef, you can view an alternative image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. In a typical January, swells large enough to cause surfable waves at Cardiff Reef run for about 75% 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.
