The Lowdown
Alright, let me look at the charts for the next 16 days. To be honest, mate, the outlook is pretty grim right now. There’s a big quiet patch leading into it for Jupiter Inlet South Jetty. We’ve got a stretch of small, weak windswell with poor surf, mostly onshore winds and small heights. That starts from Monday, the 24th of August and runs all the way through until the morning of Thursday, the 3rd of September. That’s a solid run of nothing to get excited about.
Water temp here sits around 86°F, which is about average for this time of year.
So, the real story starts on Thursday, the 3rd of September. We finally see a shift. The morning is the pick with light offshore wind from the WSW at 6 mph keeping it clean. The swell is small at 2ft but it’s coming from the E with a period of 14 seconds – that’s proper groundswell, giving the waves some shape and push even though the size is tiny. The combined energy is moderate at (208). This is the standout of the whole forecast. It won't be big, but for a spot that’s been flat and choppy for days, it'll feel like a gift. Expect it to be only for experienced surfers because it's a jetty break with an incoming groundswell, which can make for tricky currents.
Friday, the 4th of September, looks good too. Morning offers a clean WSW offshore at 6 mph. The swell holds at 2ft from the ENE, with a 13 second period and moderate energy (186). But the real treat is Friday afternoon, with glassy conditions thanks to a light SW breeze at 3 mph. That’ll be smooth and clean. The crowd factor here is “often,” so expect company on these small, clean days.
Saturday the 5th and Sunday the 6th of September keep the trend going. Offshore winds from the W and WNW, around 9 mph. Still tiny, 2ft to 2ft from the ENE, period around 11-12 seconds. Energy drops back into the double digits – (121) and (89) – so not as powerful. Still clean, but more of a longboard or funboard wave.
After that, Monday the 7th of September starts with a glassy morning, then winds switch onshore by the afternoon and it gets messy again heading into the second week.
Honestly, the best on offer is the Thursday the 3rd of September morning session. That’s the real standout: glassy offshore wind, a touch of E groundswell at 2ft with a 14-second pulse, delivering moderate energy (208). It’s not a classic, but it’s the best wave in a very quiet period.
