The Lowdown

Alright folks, it’s Rusty here. Let’s cut to the chase. The forecast for the Jupiter Inlet South Jetty area is looking pretty flat and uninspiring for the next couple of weeks. There’s a real dry spell on the cards, with the first solid opportunity not popping up until early September.

We’ve got a long stretch of poor to non-existent surf right through the end of August and into the first week of September. Swell heights are tiny, mostly hovering around 0.7ft to 2ft, with short periods and weak energy. The wind is mostly cross-on or onshore, keeping things messy. The water temp is about average for this time of year, nothing to write home about.

The first real glimmer of hope comes on Wednesday, September 9th. The morning session looks like the standout. We’re seeing a clean 2ft swell from the NE with a decent 11-second period, which gives it a bit of push. The combined energy is moderate (175), and with a light offshore wind from the WSW, it’ll be clean and glassy. This is an advanced break, so it’s not for beginners, but for those who know the jetty, it’ll offer some long-period groundswell lines. The only downside is the swell direction is a touch off the optimum, and crowds are often a factor here, so expect company. The afternoon on the 9th gets a bit bigger (3ft) but the wind swings side-on, making it less appealing.

After that, it fades again. By Thursday the 10th we’ve got a bit of NE swell but it’s dropping fast, and the wind picks up, so it’s a pass. The rest of the second week looks like more of the same – tiny, weak, and mostly blown out. There’s a brief window on Tuesday the 8th with glassy conditions, but the swell is a paltry 1ft with only 60 units of energy, so it’s barely worth a paddle.

Honestly, if you’re hanging out for a wave, mark your calendar for the morning of Wednesday the 9th. Otherwise, it’s a long stretch of flatness. Kite surfers might find the windier days more interesting, but for a paddle surfer, it’s a tough watch.

Rusty.
