Estadísticas de Olas para Doura, diciembre: Olas con Vientos Ligeros o Terrales

This image shows only the swells directed at Doura that coincided with light winds or offshore conditions over a normal December. It is based on 2705 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 red shows the biggest swells, greater than >3m (>10ft). In each graph, 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 longest spokes, was NW, 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 48% of the time, equivalent to 14 days. Open water swells exceeding >3m (>10ft) only happen 4% of the time in a typical December, equivalent to just one day but 21% of the time we expect swell in the range 2-3m (6.5-10ft) 21%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Doura is slightly protected from open water swells, we estimate that clean surf can be found at Doura about 48% of the time and that surf is spoilt by onshore wind 29% of the time. This is means that we expect 23 days with waves in a typical December, of which 14 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.
