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 through a typical February. It is based on 1808 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red shows highest swells greater than >3m (>10ft). 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 longest spokes, was NE, whereas the the dominant wind blows from the ESE. 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 ratio 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 estimate that clean surf can be found at Jupiter Inlet South Jetty about 4% of the time and that surf is spoilt by onshore wind 18% of the time. This is means that we expect 6 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.
