Azurara Swell Statistics, All Year: Surf with Light or Offshore Winds
The rose diagram shows only the swells directed at Azurara that coincided with light winds or offshore conditions over a normal year and is based upon 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and biggest 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 occurs.
The diagram suggests that the prevailing swell direction, shown by the largest spokes, was WNW, whereas the the prevailing wind blows from the NNW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 30% of the time, equivalent to 110 days. Expect open water swells to exceed >3m (>10ft) 1.2% of the time (4 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Azurara is exposed to open water swells, we calculate that clean surf can be found at Azurara about 30% of the time and that surf is blown out by onshore wind 65% of the time. This is means that we expect 347 days with waves in a typical year, of which 110 days should be surfable.
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.
