The Lowdown
Alright folks, let's get real. We are looking at a long, flat dry spell for the next 16 days. No good surf on the menu at all.
Let’s talk about Jupiter Inlet South Jetty. The water’s sitting at about 87°, which is a touch warmer than normal for late August, so it feels nice for a dip.
From Tuesday the 25th of August all the way through to Wednesday the 9th of September, it’s the same story: poor conditions. The biggest swell we see is a measly 3ft on the morning of Saturday the 29th of August. That comes from the ESE with a period of just 4 seconds—that’s short-period, local wind chop with no grunt. The combined wave energy peaks at a low 42 on the 30th (weak energy). There’s simply no power behind it.
Winds are mostly cross-onshore or onshore, often a moderate breeze, keeping the surface choppy and sloppy. There’s a brief moment on the 2nd of September morning with lighter winds, but the swell is still just 2ft of weak, short-period stuff. It’s not worth the effort.
With that onshore wind and flat conditions, this beach and jetty setup looks more like a kiteboarding spot right now. Don't bother paddling out. We’ll have to wait and see if things pick up.
