Estadísticas de Olas para Avalanche, marzo: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Avalanche that coincided with light winds or offshore conditions through a typical March and is based upon 2220 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 represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell occurs.
The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was W, whereas the the prevailing wind blows from the WSW. 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 19% of the time, equivalent to 6 days. Open water swells exceeding >3m (>10ft) only happen 3% of the time in a typical March, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Avalanche is exposed to open water swells, we calculate that clean surf can be found at Avalanche about 19% of the time and that surf is spoilt by onshore wind 80% of the time. This is means that we expect 31 days with waves in a typical March, 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.
