The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Jupiter Inlet South Jetty.
Honestly, mate, it’s a tough stretch. For the first week and a half, we’re staring down a real flat spell. From Thursday the 27th of August all the way through to Saturday the 5th of September, the surf is just not happening. We’re looking at tiny dribbles of 0.7ft to 2ft swell with next to no energy (combined energy mostly in the teens to low 30s) and mainly onshore winds. It’s a total write-off for paddle surfing. You’d be better off with a kite if the wind picks up, but even then, it’s a struggle.
We do get a small glimmer of hope on Sunday the 6th of September. The morning shows a little bump of 2ft from the NNE with a light cross-offshore breeze, so the waves will be clean. The energy is still weak at 74, but it’s surfable. That’s the best we’ve seen in a while.
The following Monday morning, the 7th of September, is another small window, with a 3ft NE swell and a clean cross-offshore wind. The energy is moderate at 156, so there’s a bit more push. Still, it’s small and not worth getting too excited about.
Wednesday the 9th of September afternoon sees a shift, with a 4ft swell from the E and a clean offshore wind from the WSW. That’s a better setup, but the period is a short 5 seconds, so the waves will be pretty weak and crumbly. The energy is moderate at 141.
If I had to pick the absolute best of the bunch, it’s the morning of Thursday the 10th of September. You’ve got a 4ft swell from the E with a clean cross-offshore breeze. The energy is weak at 88, but it’s the cleanest conditions of the entire forecast. The swell direction is from the east, which is off the optimum NE for this jetty, so it won’t be perfect, but it’s the closest we get to a decent session.
Water temp is about average for this time of year, so no surprises there.
It’s a lean run, folks. The waiting game is on.
Rusty.
