Estadísticas de Olas para Armadale Bay, Otoño: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Armadale Bay that coincided with light winds or offshore conditions over a normal northern hemisphere autumn and is based upon 7252 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 illustrate increasing swell sizes and red represents largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.
The diagram suggests that the prevailing swell direction, shown by the longest spokes, was WNW, whereas the the most common wind blows from the SW. 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 42% of the time, equivalent to 38 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (5 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Armadale Bay is exposed to open water swells, we think that that clean surf can be found at Armadale Bay about 42% of the time and that surf is messed up by onshore wind 45% of the time. This is means that we expect 79 days with waves in a typical northern hemisphere autumn, of which 38 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.
