Armadale Bay Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Armadale Bay that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 6580 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the longest spokes, was WNW, whereas the the most common 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 37% of the time, equivalent to 34 days. Expect open water swells to exceed >3m (>10ft) 4% of the time (4 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Armadale Bay is exposed to open water swells, we think that that clean surf can be found at Armadale Bay about 37% of the time and that surf is spoilt by onshore wind 52% of the time. This is means that we expect 81 days with waves in a typical northern hemisphere spring, of which 34 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.
