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

The rose diagram shows only the swells directed at Imperial Pier (North and South) that coincided with light winds or offshore conditions over a normal May. It is based on 2838 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 highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the biggest spokes, was SW, whereas the the dominant wind blows from the W. 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 26% of the time, equivalent to 8 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal May but 7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 7%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with expected 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 26% of the time and that surf is messed up by onshore wind 66% of the time. This is means that we expect 29 days with waves in a typical May, of which 8 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.
