Estadísticas de Olas para Imperial Pier (North and South), diciembre: 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 over a normal December. It is based on 2705 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 red shows the biggest swells, greater than >3m (>10ft). In both graphs, 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 biggest spokes, was WSW, whereas the the prevailing 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 42% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal December but 13% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 13%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Imperial Pier (North and South) is exposed to open water swells, we calculate that clean surf can be found at Imperial Pier (North and South) about 42% of the time and that surf is spoilt by onshore wind 57% of the time. This is means that we expect 30 days with waves in a typical December, of which 13 days should be clean enough to surf.

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.
