Zippers-Costa Azul Swell Statistics, Spring: 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 northern hemisphere spring and is based upon 6580 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and largest 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 happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the most common 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 80% of the time, equivalent to 73 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere spring but 30% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 30%, equivalent to (27 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Zippers-Costa Azul is exposed to open water swells, we estimate that clean surf can be found at Zippers-Costa Azul about 80% of the time and that surf is messed up by onshore wind 6% of the time. This is means that we expect 78 days with waves in a typical northern hemisphere spring, of which 73 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.
