Zud Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Zud that coincided with light winds or offshore conditions over a normal northern hemisphere spring. It is based on 6554 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 show increasing swell sizes and red shows highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the largest spokes, was NNW (which was the same as the dominant wind direction). 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 20% of the time, equivalent to 18 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere spring. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Zud is exposed to open water swells, we calculate that clean surf can be found at Zud about 20% of the time and that surf is blown out by onshore wind 24% of the time. This is means that we expect 40 days with waves in a typical northern hemisphere spring, of which 18 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.
