Cartagena - Hilton Surf Stats

This chart illustrates the combination of swells directed at Cartagena - Hilton through a typical November and is based upon 3347 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coastline so we have chosen the optimum grid node based on what we know about Cartagena - Hilton. In the case of Cartagena - Hilton, the best grid node is 50 km away (31 miles). The rose diagram describes the distribution of swell sizes and swell direction, while the graph at the bottom shows the same thing but without direction information. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These were forecast only 86% of the time. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens. The diagram implies that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the most common wind blows from the NE. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Cartagena - Hilton and offshore. We group these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Cartagena - Hilton, you can select a similar diagram that shows only the swells that were expected to coincide with glassy or offshore wind conditions. Over an average November, swells large enough to cause good for surfing waves at Cartagena - Hilton run for about 0% of the time.
