Urca da Conceicao Swell Statistics, September: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Urca da Conceicao that coincided with light winds or offshore conditions through a typical September. It is based on 2880 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 red represents highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the longest spokes, was N, whereas the the dominant wind blows from the ESE. 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 0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Urca da Conceicao is exposed to open water swells, we calculate that clean surf can be found at Urca da Conceicao about 0% of the time and that surf is messed up by onshore wind 21% of the time. This is means that we expect 6 days with waves in a typical September, of which 0 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.
