Japs Swell Statistics, Julho: Surf with Light or Offshore Winds

This image shows only the swells directed at Japs that coincided with light winds or offshore conditions over a normal July. It is based on 2976 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 illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the largest spokes, was SW, whereas the the dominant wind blows from the NW. 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 54% of the time, equivalent to 17 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical July, equivalent to just one day but 27% of the time we expect swell in the range 2-3m (6.5-10ft) 27%, equivalent to (8 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Japs is exposed to open water swells, we estimate that clean surf can be found at Japs about 54% of the time and that surf is spoilt by onshore wind 40% of the time. This is means that we expect 29 days with waves in a typical July, of which 17 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.
