Estadísticas de Olas para Arroyo Laguna, noviembre: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Arroyo Laguna that coincided with light winds or offshore conditions through a typical November. It is based on 2387 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.
The diagram implies that the dominant swell direction, shown by the longest spokes, was WSW, whereas the the most common wind blows from the NNW. 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal November. Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Arroyo Laguna is exposed to open water swells, we calculate that clean surf can be found at Arroyo Laguna about 4% of the time and that surf is messed up by onshore wind 7% of the time. This is means that we expect 3 days with waves in a typical November, 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.
