Jupiter Inlet South Jetty Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Jupiter Inlet South Jetty that coincided with light winds or offshore conditions through a typical northern hemisphere winter and is based upon 7765 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 represent increasing swell sizes and red illustrates largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was NE, whereas the the most common wind blows from the E. 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 6% of the time, equivalent to 5 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere winter but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Jupiter Inlet South Jetty is slightly protected from open water swells, we calculate that clean surf can be found at Jupiter Inlet South Jetty about 6% of the time and that surf is spoilt by onshore wind 22% of the time. This is means that we expect 25 days with waves in a typical northern hemisphere winter, of which 5 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.
