The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the Jupiter Inlet South Jetty area across this 16-day stretch.
Right off the bat, I gotta be straight with you — this is a rough run. We’re talkin’ a long, flat spell with nothing worth paddlin’ out for. The first handful of days are dead calm with tiny dribbles. Sunday the 6th and Monday the 7th are seein’ barely a ripple, with swell heights around 0.7ft to 1ft, weak wave energy (6 to 9 on the scale), and winds that are offshore or glassy but there’s just no push. The water’s sittin’ at 87°F, which is a touch warmer than usual for this time of year, but that don’t help the surf.
Tuesday the 8th teases a bit with a long-period groundswell from the NE at 11 seconds and 1ft swell. Still tiny, energy only up to 40, so it’s not gonna get you wet properly. By Wednesday the 9th we finally see some increase — swell hits 3ft from the NE, period drops to 9 seconds, and energy climbs to 131 (moderate), but the wind is cross-onshore from the ESE at 15 km/h, so it’s choppy and messy. Poor surf conditions, plain and simple. Not a single day in this whole outlook gets a recommendation worth shoutin’ about.
The rest of the run through to late September continues the same sad story: swell never gets over 3ft, period mostly short (4 to 9 seconds), and winds are onshore or cross-onshore the whole way. Energy stays low — mostly two-digit numbers in the teens and twenties, with only a brief moderate bump on the 9th. This spot is a beach/jetty setup, and with these weak, wind-chopped waves, it’s honestly better suited for a kite than a paddle board. There’s nothing here that would get my heart racin’. Forecasts can change, but right now, we’re in a dry spell.
Stay patient, check back later. We’ll get a pulse again eventually.
Rusty.
