The Lowdown

Alright folks, Rusty here. Let’s chew the fat on what’s coming for the Jupiter Inlet.

Truth is, we’re in for a dry spell. There’s a big ol’ gap with nothing worth paddling for. The first real chance doesn’t show up until Wednesday, 9th September, so you’ve got a full week of tiny, choppy junk to sit through before anything clicks.

Your best bet lands on Wednesday, 9th September at Jupiter Inlet South Jetty. That’s when a north-east swell rolls in at 3ft with a 10-second period – period’s not super long, but it’s enough to shape up some peaks. The combined wave energy sits at 171 (moderate), so there’s some grunt. Morning brings clear skies and glassy conditions (wind from the WNW at 0 km/h), so the surface will be clean as a whistle. This is the one to circle.

Water temp is a warm 86°, about 1° above average – pretty standard for this time of year, no craziness.

That Wednesday afternoon, the wind swings ENE at 12 mph and turns cross-onshore, so things get a bit lumpy. Swell holds around 3ft, but it’s not as pretty.

Thursday, 10th September still has some leftover NE swell at 3ft with a 10-second period, and morning glass (E at 6 mph). Wave energy is moderate at 121. It’s not the standout, but it’ll get you wet.

After that, it’s all downhill. From 11th September onward, we’re lookin’ at knee-high slop – mostly under 2ft – with onshore breezes. Not a single highlight in the second week.

Just the Jetty in the data. If you’re a beginner, those 3ft days are fine, but the current near the rocks can be tricky. Crowds are “often,” so expect a crew out there for that Wednesday morning glass-off.

Bottom line: Wednesday morning, 9th September is your shot. Clean, glassy, a little push from the NE. Get out there and make it count.

Rusty.
