The Lowdown
Alright, let’s break down this stretch for Jupiter Inlet South Jetty. I’ve looked over all the data, and honestly, it’s a tough pill to swallow.
The first week is a complete wash. We’re talking ankle to knee high waves, barely a ripple. Swell heights are stuck between 0.5ft and 2ft, and the overall energy is just weak, often in the low readings. There’s a bit of a bump on the 7th with a 4ft swell and the energy getting up to 111, and the 8th steps it up slightly to 4ft with 118 energy. But it’s all wind-blown slop. The winds are howling 15-25 mph out of the east and ENE, chopping up any potential. It’s a mess.
Then, from the 10th through the 17th, we hit a massive lull. The 10th and 11th show a 4ft swell again, but the juice is gone, energy in the 70s, and the onshore winds keep it all messy. After that, it just dies completely. We're back down to under 2ft, with energy readings in the single digits and low teens. It’s a dead ocean, a blank period that’s gonna test your patience.
Water temp is a warm 85°F with no real anomaly, so it’s still good for a swim, but not for surfing. With a break like this being “fairly consistent” the dead spell is more of a fluke. The ocean always comes back. Hang tight, and check back soon.
This is Rusty, out.
