Arrifana Swell Statistics, Novembro: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Arrifana that coincided with light winds or offshore conditions over a normal November. It is based on 2867 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 red represents 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 dominant swell direction, shown by the biggest spokes, was NW, whereas the the most common wind blows from the N. 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 37% of the time, equivalent to 11 days. Open water swells exceeding >3m (>10ft) only arise 2% of the time in a typical November, equivalent to just one day but 14% of the time we expect swell in the range 2-3m (6.5-10ft) 14%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Arrifana is slightly protected from open water swells, we estimate that clean surf can be found at Arrifana about 37% of the time and that surf is blown out by onshore wind 34% of the time. This is means that we expect 21 days with waves in a typical November, of which 11 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.
