Zippers-Costa Azul Swell Statistics, October: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Zippers-Costa Azul that coincided with light winds or offshore conditions through a typical October and is based upon 2480 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 biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the prevailing 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 73% of the time, equivalent to 23 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal October but 23% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 23%, equivalent to (7 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Zippers-Costa Azul is exposed to open water swells, we calculate that clean surf can be found at Zippers-Costa Azul about 73% of the time and that surf is messed up by onshore wind 15% of the time. This is means that we expect 27 days with waves in a typical October, of which 23 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.
