Nungwi Reefs Swell Statistics, November: Surf with Light or Offshore Winds

This image shows only the swells directed at Nungwi Reefs that coincided with light winds or offshore conditions through a typical November and is based upon 2387 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red shows largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was ESE (which was the same as the most common 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 40% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November. Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Nungwi Reefs is exposed to open water swells, we calculate that clean surf can be found at Nungwi Reefs about 40% of the time and that surf is messed up by onshore wind 58% of the time. This is means that we expect 29 days with waves in a typical November, of which 12 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.
