Aha Rivermouth Swell Statistics, Summer: 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 northern hemisphere summer. It is based on 7266 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 red shows the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the longest spokes, was E, whereas the the most common wind blows from the SSE. 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 23% of the time, equivalent to 21 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer but 3% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 3%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Aha Rivermouth is exposed to open water swells, we calculate that clean surf can be found at Aha Rivermouth about 23% of the time and that surf is blown out by onshore wind 19% of the time. This is means that we expect 38 days with waves in a typical northern hemisphere summer, of which 21 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.
