Praia dos Castelhanos (Ilha Bela) Surf Stats

All swells

(any wind direction)

Good Surf

(light / offshore wind)

The rose diagram shows the range of swells directed at Praia dos Castelhanos (Ilha Bela) over a normal March and is based upon 3460 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind or surf right at the shore so we have chosen the most applicable grid node based on what we know about Praia dos Castelhanos (Ilha Bela), and at Praia dos Castelhanos (Ilha Bela) the best grid node is 27 km away (17 miles). The rose diagram shows the distribution of swell directions and swell sizes, 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 occurred only 48% of the time. Green and yellow illustrate increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs. The diagram suggests that the most common swell direction, shown by the longest spokes, was ESE, whereas the the prevailing wind blows from the E. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Praia dos Castelhanos (Ilha Bela) and out to sea. We group these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose plot. Because wind determines whether or not waves are good for surfing at Praia dos Castelhanos (Ilha Bela), you can view an alternative image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical March, swells large enough to cause clean enough to surf waves at Praia dos Castelhanos (Ilha Bela) run for about 52% of the time.
