The Lowdown

Alright, Rusty here again, but in feet and miles. Let’s get into it.

Look, the Jupiter Inlet South Jetty is pretty much asleep for the next couple of weeks. From Saturday the 29th of August all the way through to Thursday the 10th of September, it’s a whole lot of nothing. Tiny swell, mostly onshore wind, and plenty of stormy weather. There are a couple of glassy mornings – like Monday the 31st of August – but the waves are just too small to surf.

Your one real chance comes on Friday the 11th of September. The morning will see a little 2ft groundswell from the NE, with a 10-second period, and the wind will be glassy – light and variable, so it’ll be smooth. The combined swell energy is a weak 71, but it’s enough for a few rides. The water’s at 86°F, which is about 2°F warmer than usual for this time of year, so it feels nice. This is an advanced wave spot, and it’s often crowded, so expect company.

Saturday the 12th of September morning brings a cross-offshore breeze from the WSW, cleaning it up a bit with the same 2ft NE swell, but still no real power.

Honestly, if you’re itching to paddle, the 11th is your only window. It’s not worth driving for, but if you’re local, you might find a fun one.

Rusty.
