Estadísticas de Olas para All Day Bay, Primavera: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at All Day Bay that coincided with light winds or offshore conditions over a normal southern hemisphere spring. It is based on 7252 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 represent increasing swell sizes and red illustrates the largest swells, greater than >3m (>10ft). In both graphs, 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 biggest spokes, was SSE, whereas the the most common wind blows from the NW. 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 33% of the time, equivalent to 30 days. Open water swells exceeding >3m (>10ft) only happen 0.7% of the time in a typical southern hemisphere spring, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (7 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that All Day Bay is exposed to open water swells, we think that that clean surf can be found at All Day Bay about 33% of the time and that surf is blown out by onshore wind 33% of the time. This is means that we expect 60 days with waves in a typical southern hemisphere spring, of which 30 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.
