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

The rose diagram shows only the swells directed at Arrieta that coincided with light winds or offshore conditions through a typical December and is based upon 2953 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 illustrate increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In both graphs, 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 biggest spokes, was NNW, whereas the the dominant 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal December. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Arrieta is quite sheltered from open water swells, we think that that clean surf can be found at Arrieta about 3% of the time and that surf is blown out by onshore wind 33% of the time. This is means that we expect 11 days with waves in a typical December, of which 1 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.
