San Miguel - Baixa de Viola Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at San Miguel - Baixa de Viola 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, 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 longest spokes, was NW, whereas the the dominant 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 26% of the time, equivalent to 24 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 fraction of these swells that coincided with expected offshore winds, and given the fact that San Miguel - Baixa de Viola is exposed to open water swells, we calculate that clean surf can be found at San Miguel - Baixa de Viola about 26% of the time and that surf is spoilt by onshore wind 48% of the time. This is means that we expect 67 days with waves in a typical northern hemisphere autumn, of which 24 days should be clean enough to surf.

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.
