Barra do Douro Swell Statistics, Febbraio: 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 through a typical February. It is based on 2440 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was WNW, whereas the the most common wind blows from the NNW. 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 35% of the time, equivalent to 10 days. Open water swells exceeding >3m (>10ft) only happen 3% of the time in a typical February, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Barra do Douro is exposed to open water swells, we estimate that clean surf can be found at Barra do Douro about 35% of the time and that surf is messed up by onshore wind 65% of the time. This is means that we expect 28 days with waves in a typical February, 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.
