Estadísticas de Olas para Arinaga, febrero: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Arinaga that coincided with light winds or offshore conditions through a typical February. It is based on 2102 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and red represents highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.
The diagram implies that the prevailing swell direction, shown by the largest spokes, was NNW, whereas the the dominant wind blows from the NNE. 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 2% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal February. Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Arinaga is quite sheltered from open water swells, we think that that clean surf can be found at Arinaga about 2% of the time and that surf is messed up by onshore wind 26% of the time. This is means that we expect 8 days with waves in a typical February, of which 1 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.
