Jupiter Inlet South Jetty Surf Forecast and Surf Report

Alright, this is Rusty. Let’s talk about what’s on the table for the next two weeks at Jupiter Inlet South Jetty (United States).

Right now, we’re looking at a pretty grim stretch to start. There’s nothing worth paddling out for from Friday the 28th of August all the way through to Monday the 7th of September. I’m talking a solid ten days of tiny, weak swell, cross-onshore breezes, and mostly poor conditions. The combined wave energy is barely a blip (32 to just 6) and the swell heights are struggling to hit 3 feet. Even the light wind days are bringing wind swell with periods around 4 to 5 seconds, which is just too short to offer any sort of rideable shape. This is a tough run for any surfer.

But hold on. Things finally change on the morning of Tuesday the 8th of September. That’s the standout in this entire outlook. We get a push of NE groundswell hitting 4 feet with a nice long period of 12 seconds, giving the jetty some real energy to work with. The combined energy jumps to 303 – that’s moderate but building. The wind early is a light WSW offshore, so it’ll be clean, with clean conditions. Swell direction NE is right on the money for this break. On the 8th, that morning window is your best shot. The afternoon sees a light cross-on breeze, so morning is the call.

The following day, Wednesday the 9th, has a similar setup: 4 feet NE swell, 11-second period, and a clean offshore wind from the west in the morning (277 combined energy). Again, the morning is the golden hour before the onshore kicks in for the afternoon.

The 10th and 11th of September both offer 3 to 4 feet NE swells with lighter winds, but the quality drops a notch. The morning conditions are described as “ordinary” — still surfable, but not the same standout quality as the 8th or 9th. Periods drop to 10 seconds.

The last day in the window, Saturday morning the 12th of September, looks like a glassy, fading swell (2 feet, 10 seconds, combined energy 110). It’s surfable for a longboard or a log, but nothing to get overly excited about.

So to sum it up: if you’ve got a board and you’re not a beginner (4 feet is solid, but manageable for intermediate and up), Tuesday the 8th or Wednesday the 9th of September are your winners. Go early, keep the offshore wind in your face, and enjoy the clean lines off the jetty. The rest of the window is pretty much dead or average. Crowds are likely at this spot, so don’t be surprised if you’re sharing waves on those good mornings.
