Cardiel (Mar del Plata) Swell Statistics, All Year: All Swell – Any Wind
The figure illustrates the range of swells directed at Cardiel (Mar del Plata) through an average year and is based upon 23151 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the coast so we have chosen the optimum grid node based on what we know about Cardiel (Mar del Plata), and at Cardiel (Mar del Plata) the best grid node is 4 km away (2 miles).
The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing without direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These were forecast only 35% of the time. Green and yellow show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the dominant swell direction, shown by the biggest spokes, was SSE, whereas the the most common wind blows from the NW. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Cardiel (Mar del Plata) and offshore. We lump these in with the no surf category of the bar chart. To keep it simple we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Cardiel (Mar del Plata), you can load a different image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. In a typical year, swells large enough to cause good for surfing waves at Cardiel (Mar del Plata) run for about 65% 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.
