Aha Rivermouth Swell Statistics, Maggio: Surf with Light or Offshore Winds

This image shows only the swells directed at Aha Rivermouth that coincided with light winds or offshore conditions over a normal May. It is based on 2838 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 represent 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 frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the longest spokes, was E, whereas the the most common 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 20% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Aha Rivermouth is exposed to open water swells, we estimate that clean surf can be found at Aha Rivermouth about 20% of the time and that surf is blown out by onshore wind 43% of the time. This is means that we expect 20 days with waves in a typical May, of which 6 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.
