The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the Jupiter Inlet South Jetty.
To be straight with you, this 16-day stretch is a tough one. For the first week and a half, we’re lookin' at a whole lot of flatness. From now all the way through to the morning of the 8th of September, there’s basically nothing worth paddling out for. Tiny scraps, poor surf conditions, and onshore or cross-onshore winds are the story – nothin’ but a frustrating wait. The water temperature is 87°, which is a touch warmer than normal for this time of year, making it feel like a bath. You’re not gonna be needing a wetsuit, but you will need patience.
That first real glimmer of hope shows up on the morning of Tuesday, the 8th of September. We finally see a pulse of weak to moderate energy (105) from the NE at 0.7 ft, with a period of 10 seconds. The wind is a light cross-offshore from the SW, giving us clean conditions. It’s not big, but it’s surfable and the jetty might start working. For an advanced spot like this, it’s a start.
The standout of the whole outlook, and the only one I’d really circle on the calendar, is the morning of Wednesday, the 9th of September. We get a clean pulse with offshore wind from the W, blowing straight out. The swell is a 3 ft NE groundswell with an 11-second period, and the energy is moderate at (175). This is the cleanest window we’ll see. The swell direction matches what this jetty likes, and with offshore wind, it’ll be lined up and hollow over the sandbar. It’s a short window though – the afternoon gets messy.
Also worth a mention, Thursday morning the 10th of September offers a smaller, clean option with 2 ft NE swell and cross-offshore WSW wind, but the energy is weaker (71). It’s a consolation prize compared to the Wednesday morning session.
Overall, don’t hold your breath until the 8th and 9th of September. Wednesday the 9th is the day to make a plan. After that, it fades back to small and scrappy through the second week, with nothing else firing.
