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

The rose diagram shows only the swells directed at Jupiter Inlet South Jetty that coincided with light winds or offshore conditions over a normal February. It is based on 1584 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 shows the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the longest spokes, was NE, whereas the the dominant 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal February. Taking into account the fraction of these swells that coincided with forecast 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 4% of the time and that surf is blown out by onshore wind 20% of the time. This is means that we expect 7 days with waves in a typical February, 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.
