Osterizers/Rainbows Swell Statistics, July: Surf with Light or Offshore Winds

This image shows only the swells directed at Osterizers/Rainbows that coincided with light winds or offshore conditions through a typical July and is based upon 2976 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 the 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 biggest spokes, was NNW, whereas the the most common wind blows from the ENE. 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal July. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Osterizers/Rainbows is slightly protected from open water swells, we calculate that clean surf can be found at Osterizers/Rainbows about 3% of the time and that surf is blown out by onshore wind 0% of the time. This is means that we expect 1 days with waves in a typical July, of which 1 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.
