Zarautz Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Zarautz that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 8475 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 highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the biggest spokes, was NW, whereas the the dominant wind blows from the SW. 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 45% of the time, equivalent to 41 days. Expect open water swells to exceed >3m (>10ft) 1.7% of the time (2 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Zarautz is exposed to open water swells, we calculate that clean surf can be found at Zarautz about 45% of the time and that surf is spoilt by onshore wind 49% of the time. This is means that we expect 86 days with waves in a typical northern hemisphere autumn, of which 41 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.
