San Miguel - Areias Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at San Miguel - Areias that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 8724 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In each graph, 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 longest spokes, was NW, whereas the the most common wind blows from the W. 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 22% of the time, equivalent to 20 days. Open water swells exceeding >3m (>10ft) only arise 1.2% of the time in a typical northern hemisphere autumn, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (9 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that San Miguel - Areias is slightly protected from open water swells, we estimate that clean surf can be found at San Miguel - Areias about 22% of the time and that surf is spoilt by onshore wind 45% of the time. This is means that we expect 61 days with waves in a typical northern hemisphere autumn, of which 20 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.
