Estadísticas de Olas para Backdoor, abril: Olas con Vientos Ligeros o Terrales

The rose diagram shows only the swells directed at Backdoor that coincided with light winds or offshore conditions over a normal April and is based upon 2640 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 show increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the NW. 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 22% of the time, equivalent to 7 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal April but 10% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 10%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Backdoor is exposed to open water swells, we calculate that clean surf can be found at Backdoor about 22% of the time and that surf is blown out by onshore wind 73% of the time. This is means that we expect 28 days with waves in a typical April, of which 7 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.
