Nungwi Reefs Swell Statistics, March: 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 March and is based upon 2716 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 show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was E (which was the same as the dominant 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 32% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal March. 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 estimate that clean surf can be found at Nungwi Reefs about 32% of the time and that surf is spoilt by onshore wind 61% of the time. This is means that we expect 29 days with waves in a typical March, 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.
