The Lowdown
G’day, it’s Rusty.
Look, I’ll be straight with you. The next couple of weeks are looking pretty damn flat and blown out for the Jupiter Inlet South Jetty. We’ve got a long stretch of tiny, weak surf ahead, so don’t be in a rush to grab your board. We’re talking about a solid run of days with nothing on the table. From Friday the 14th right through to the morning of Thursday the 28th, it’s all showing as poor surf conditions. The swell energy is almost non-existent, mostly single digits and low double digits, like 8, 9, 34, or 13. Wind’s mostly cross-onshore or onshore, which chops up what little is there. There’s a bit of glass early on the 16th and again on the morning of the 20th, but with waves around 0.7ft, it’s not doing anyone any favors.
The water temp is sitting at 86°, which is about 1° warmer than the long-term average for this time of year. So, it’s not a big deal, just a touch on the warm side. Nothing to write home about.
The first real glimmer of hope shows up on the morning of Friday the 28th. The energy finally kicks up past that weak zone, hitting 101, with a clean cross-offshore breeze. Swell direction is ESE at 1ft, with a period of 12 seconds. That’s a long-period groundswell, and it’s still small, but it’s the first sign of life. The afternoon gets glassy with the energy up to 129 and surfable, but still very ordinary. That’s the first day you’d even bother looking at the ocean.
Then Saturday the 29th morning looks better. We’ve got a proper offshore wind from the W at 6 mph, and the swell is up to 2ft from ENE, with the energy jumping to 172. The period is still a solid 12 seconds. This is shaping up to be the best of the run. It’s not huge, but it’s clean and lined up. The afternoon sees the energy spike to 287 with the swell pushing to 3ft from ENE, but the wind swings cross-onshore, so it’ll get a bit bumpy. Still, that Saturday morning is the standout.
So, mark your calendar for the 28th and 29th. After nearly two weeks of nothing, that’s the window. It’s a jetty, so it handles a long-period swell better than a lot of beach breaks, and the direction is right in the NE optimum. The 2ft on Saturday morning is clean, and that’s the one to go for. It’s not a day for beginners, but the jetty keeps it interesting. Crowds are likely, so get there early.
The long-range stuff is promising, but you know how it is – two weeks out, forecasts can change. Still, there’s something to chase.
Rusty.
