The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Jupiter Inlet South Jetty over the next couple of weeks.
Straight up, I gotta be honest with you – this is a tough stretch. The forecast is lookin' pretty flat and raggedy for the most part, with a long gap of nothing worthwhile. The water’s sittin' at 86°F on the 10th, which is about 0.5°F warmer than normal, so pretty average for this time of year.
The first proper surf window is a long way off. We’ve got a real dry spell from the 10th of August right through to the morning of the 19th. That’s over a week of small, weak, and messy conditions. The swell energy is basically non-existent, with readings like 20 (weak energy) on the 10th and barely a ripple after that. Winds are mostly cross-on or onshore, choppin' up what little bump there is. A few glassy moments pop up on the 12th morning and the 17th morning, but with swell heights of just 0.3ft to 0.7ft, there’s nothing to ride.
The real standout, the only window that even gets me excited, is the morning of Wednesday the 19th of August. We’ve got a clean, glassy surface with a calm wind, and a little push of swell from the ENE at 1.0ft. The period is 12 seconds, so that’s a proper groundswell, not just wind chop. The combined energy hits 38 (still weak energy, but the best of the bunch). Now, this is a jetty and beach setup, so a long-period swell like this can make the waves a bit straight and fast, but with the offshore wind and glassy conditions, it’s the cleanest you’ll see it. This is for advanced surfers only, as the jetty can be tricky, and the crowds are often around. If you’re keen, that’s your best shot.
After that, the afternoon of the 19th gets messy again with cross-on wind, and the rest of the run into the 25th is more of the same: small, onshore, and poor. The 23rd and 24th see a slight bump to 2ft - 2ft but with short period (4-5 seconds) and onshore winds, it’s just choppy junk.
So, bottom line: it’s a long wait for a very short, clean window on the 19th morning. If you’re desperate, you could paddle out then, but don’t expect much. The rest of the month is a write-off for surf at Jupiter Inlet.
