Statistiques de Surf de Motiti Island - Kaiwakawaka ree

This picture shows the combination of swells directed at Motiti Island - Kaiwakawaka ree through a typical October and is based upon 3471 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 Motiti Island - Kaiwakawaka ree. In the case of Motiti Island - Kaiwakawaka ree, the best grid node is 15 km away (9 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 occurred only 64% 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 largest spokes, was NE, whereas the the prevailing wind blows from the W. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Motiti Island - Kaiwakawaka ree and out to sea. We combine these with the no surf category of the bar chart. To keep it simple we don't show these in the rose plot. Because wind determines whether or not waves are clean enough to surf at Motiti Island - Kaiwakawaka ree, you can load a different image that shows only the swells that were expected to coincide with glassy or offshore wind conditions.
