Arica Swell Statistics, May: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Arica that coincided with light winds or offshore conditions through a typical May and is based upon 2200 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 largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was SSW, whereas the the most common wind blows from the S. 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 1.1% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Arica is exposed to open water swells, we calculate that clean surf can be found at Arica about 1.1% of the time and that surf is messed up by onshore wind 99% of the time. This is means that we expect 31 days with waves in a typical May, of which 0 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.
