Zambujeira do Mar Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Zambujeira do Mar that coincided with light winds or offshore conditions through a typical northern hemisphere winter and is based upon 6931 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and red represents the 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 WNW, whereas the the dominant wind blows from the N. 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 36% of the time, equivalent to 33 days. Open water swells exceeding >3m (>10ft) only occur 1.5% of the time in a typical northern hemisphere winter, equivalent to just one day but 13% of the time we expect swell in the range 2-3m (6.5-10ft) 13%, equivalent to (12 days). Taking into account the ratio of these swells that coincided with expected offshore winds we estimate that clean surf can be found at Zambujeira do Mar about 36% of the time and that surf is spoilt by onshore wind 60% of the time. This is means that we expect 87 days with waves in a typical northern hemisphere winter, of which 33 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.
