Estadísticas de Olas para Apache Pier, septiembre: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Apache Pier that coincided with light winds or offshore conditions through a typical September and is based upon 2400 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 shows largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the prevailing swell direction, shown by the longest spokes, was SE, whereas the the most common wind blows from the E. 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 20% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal September. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Apache Pier is exposed to open water swells, we calculate that clean surf can be found at Apache Pier about 20% of the time and that surf is blown out by onshore wind 54% of the time. This is means that we expect 22 days with waves in a typical September, of which 6 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.
