San Miguel - Baixa de Viola Swell Statistics, March: 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 March and is based upon 2964 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 represent increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was NW, whereas the the prevailing wind blows from the WSW. 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 31% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal March but 17% of the time we expect swell in the range 2-3m (6.5-10ft) 17%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that San Miguel - Baixa de Viola is exposed to open water swells, we think that that clean surf can be found at San Miguel - Baixa de Viola about 31% of the time and that surf is messed up by onshore wind 43% of the time. This is means that we expect 23 days with waves in a typical March, of which 10 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.
