The Lowdown

Alright, this is Rusty. Let’s talk about what’s happening at Jupiter Inlet South Jetty. First off, I gotta be straight with you – the next two weeks are looking pretty bleak. We’ve got a long stretch of small, weak, and messy conditions. The water temp is sitting right around 86° with a teeny anomaly of 0.7°, so that’s totally normal for this time of year.

The first real glimmer of anything surfable? You’re gonna have to wait until Monday the 17th. That morning, the wind swings around to a light cross-offshore from the NW at 3 mph, and the swell jumps a bit to 1 ft from the NNE. Wave energy is still weak (26), but it’s clean. That’s the best we’ve got for a while, and it’s not a standout – just a little window of okay conditions.

The next morning, Tuesday the 18th, is similar. A light cross-offshore from the NNW at 6 mph, with 2 ft from the NE. The energy is still low (46), and the period is a short 7 seconds, so no real grunt. It’s clean, but don’t expect much power.

Then on Wednesday the 19th, we get a glassy morning with the wind dropping to nothing from the NW, and a tiny 0.7 ft from the ESE with a longer period of 10 seconds. It’s clean, but it’s barely a ripple. Energy is only 26.

Thursday the 20th morning is dead flat and glassy – 0.7 ft from the ENE, period 9 seconds, and the wind is calm. That’s as close to a lake as we’re gonna get.

The rest of the run through to the 26th is just a mix of onshore wind, tiny windswell, and rotten conditions. The combined energy of all swells never gets into the triple digits, staying weak the whole time. For a break that’s fairly exposed to NE swell, and with the optimum direction being NE, we just aren’t getting the goods.

If you’re a kitesurfer, those afternoons with onshore winds and a bit of chop might be more interesting than anything for a paddle surfer. The jetty setup can be tricky, and with the crowds sometimes being an issue, it’s not worth fighting for these scraps.

Honestly, hang tight. The forecast can change, but right now, there’s nothing to get excited about. We’ve got a solid blank run from now until at least the 17th, and even then, it’s just barely rideable. Keep your eyes on the horizon, but don’t hold your breath.

Rusty.
