Estadísticas de Olas para Imperial Pier (North and South), Primavera: Olas con Vientos Ligeros o Terrales

This image shows only the swells directed at Imperial Pier (North and South) that coincided with light winds or offshore conditions through a typical northern hemisphere spring and is based upon 8682 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 red represents the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the longest spokes, was WSW, whereas the the most common wind blows from the WNW. 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 27% of the time, equivalent to 25 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere spring but 1.9% of the time we expect swell in the range 2-3m (6.5-10ft) 1.9%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Imperial Pier (North and South) is exposed to open water swells, we think that that clean surf can be found at Imperial Pier (North and South) about 27% of the time and that surf is messed up by onshore wind 66% of the time. This is means that we expect 85 days with waves in a typical northern hemisphere spring, of which 25 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.
