Estadísticas de Olas para Asu, noviembre: Olas con Vientos Ligeros o Terrales
The rose diagram shows only the swells directed at Asu that coincided with light winds or offshore conditions through a typical November and is based upon 2387 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 show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the most common swell direction, shown by the longest spokes, was SSW, whereas the the dominant wind blows from the W. 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 56% of the time, equivalent to 17 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal November but 33% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 33%, equivalent to (10 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Asu is exposed to open water swells, we estimate that clean surf can be found at Asu about 56% of the time and that surf is spoilt by onshore wind 44% of the time. This is means that we expect 30 days with waves in a typical November, of which 17 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.
