Barra do Douro Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Barra do Douro that coincided with light winds or offshore conditions over a normal northern hemisphere winter and is based upon 7765 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 represent increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the ENE. 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 39% of the time, equivalent to 35 days. Expect open water swells to exceed >3m (>10ft) 3% of the time (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Barra do Douro is exposed to open water swells, we think that that clean surf can be found at Barra do Douro about 39% of the time and that surf is blown out by onshore wind 59% of the time. This is means that we expect 89 days with waves in a typical northern hemisphere winter, of which 35 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.
