Table - best surf conditions forecast for Jupiter Inlet South Jetty over the next 16 days.
The Lowdown
Alright folks, Rusty here. Let me level with you. The outlook for the next 16 days is a tough one. I've scanned every bit of the forecast and there's really nothing that qualifies as a proper surf session. We're looking at a long stretch with no recommendations at all from September 4th right through to September 19th. That's a solid two and a half weeks of flat or poor conditions.
The main issue is the lack of any real swell energy. The best we see is a weak pulse of moderate energy (140) on the morning of the 9th, with a swell of 3ft from the NE, but the wind is onshore, which will ruin any chance of a clean wave. The water temperature at Jupiter Inlet South Jetty is at 87°F, which is a touch warmer than normal for this time of year, but it's not going to help the surf.
You'll see a few mornings with glassy or clean conditions, like the morning of the 8th with a glassy wind and a weak 1.0ft swell, but that's ankle-snappers at best. The period on that one is 11 seconds, which is okay, but there's just no push behind it. Later, like on the morning of the 15th, we get a bump of moderate energy (106) with a 3ft NE swell, but again, the wind is onshore from the east. It's looking more like a kiteboarding setup than a paddle session.
Forget about any standout days. There are no good options on the table. The break is Jupiter Inlet South Jetty, a beach and jetty setup that's advanced-level, but it's not going to be breaking with any quality. The crowds are often around here, but they won't be out for this. It's a frustrating run, but that's the way it is sometimes. Forecasts can change, but for now, the board stays in the van.
Rusty.
