Statistiques de Houle pour Narrabeen-North, Toute l'Année: Toutes Houles – Tous Vents

The graph shows the range of swells directed at Narrabeen-North through a typical year. It is based on 33228 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 best grid node based on what we know about Narrabeen-North. In the case of Narrabeen-North, the best grid node is 28 km away (17 miles).

The rose diagram illustrates the distribution of swell sizes and directions, 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 occurred only 56% of the time. Green and yellow show increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was E, whereas the the prevailing wind blows from the SW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Narrabeen-North and out to sea. We lump these in 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 Narrabeen-North, you can load a different image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. Over an average year, swells large enough to cause surfable waves at Narrabeen-North run for about 44% 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.
