The Lowdown
Alright, this is Rusty. Let me tell you, it’s been a rough stretch here at Jupiter Inlet South Jetty. We’re looking at a long, dry spell with basically nothing worth paddling out for right through the end of this forecast period. The first real recommendation doesn’t even appear in the data, and it stays that way for the entire 16-day window. Every single entry is flagged as "poor surf conditions." We’re talking about a solid two-and-a-half-week gap here, from Sunday the 9th of August all the way to Monday the 24th of August, with zero on offer.
The water temperature is sitting at 85°F with a 0.4°F anomaly, so it’s about average for the time of year. That’s about the only thing that’s normal. The combined swell energy is weak, barely cracking double digits, usually sitting between 4 and 52 (52). It’s all tiny, short-period windswell—under 3ft—with periods mostly between 4 and 9 seconds, which is just sloppy and gutless.
Winds are a constant problem. It’s mostly cross-onshore from the ESE or SE at 12-12 mph, or even straight onshore, which chops up the already tiny surf. There is one brief moment on the morning of Wednesday the 12th of August where it goes glassy with a 0.3ft NE swell, but that’s barely a ripple. On Monday the 17th of August, we get a clean offshore breeze from the WNW, but again, it’s on a tiny 1ft NNE swell.
Honestly, if you’re looking for a paddle, you’re better off staying home. This is about as blank as it gets for this area, and with these constant onshore winds and weak energy, the setup looks far more interesting for kite surfing than paddle surfing right now. Hang in there, things can change.
