Conditions at Jupiter Inlet in September
September: A Rising Pulse
The tropics and early fall fronts inject life back into Jupiter. Average swell height climbs back to 3-4ft (1.0m), and the period stretches to 8.2s. NE and ENE swells combine for a massive 62% of all observations, with a notable bump in the 1.5-2.5m (5-8ft) range. The issue is wind: ENE and E winds blow 14-15% of the time, right onshore. Still, 16% of hours offer clean offshore flow, and those post-frontal or pre-hurricane windows can be world-class. Water remains warm at 28.8°C, air averages 27.6°C, and rainfall is high at 6.5mm/day.
