Upper Sereweh Swell Statistics, November: Surf with Light or Offshore Winds

This image shows only the swells directed at Upper Sereweh that coincided with light winds or offshore conditions through a typical November and is based upon 2867 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 largest 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 prevailing swell direction, shown by the largest spokes, was SW, 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 34% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November but 21% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 21%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Upper Sereweh is exposed to open water swells, we estimate that clean surf can be found at Upper Sereweh about 34% of the time and that surf is spoilt by onshore wind 66% of the time. This is means that we expect 30 days with waves in a typical November, of which 10 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.
