The Lowdown
Alright folks, let’s talk straight. It’s Rusty, and I’m here to tell you the ocean is lookin’ like a lake for a while. We’ve got a long flat spell on our hands, so don’t be in a rush to wax up.
From the 7th all the way through the 19th, it’s gonna be pretty dead. We see some tiny northeast pulses, 0.2 to 0.4 feet, but there’s no power behind them. The combined energy is weak, mostly under 50. There’s a small bump on the 9th and 10th with 3 to 4 feet of swell, but the period is short and the wind’s going to mess it up. It’s just not surfable. The water is about normal temperature for the season, no big deal. So, we’re lookin’ at a gap with no real surf for about 12 days. It’s a tough stretch, for sure.
Now, the first real glimmer of hope shows up on the morning of the 20th of September. We get a small pulse of 2 feet from the northeast, with a period of 7 seconds. The wind will be offshore, blowing from the west-southwest at 9 mph, and it’s gonna be clean. The energy is still moderate, reading at 52. It’s small, but the surface will be glassy. This is your chance to get out at Jupiter Inlet South Jetty. It’s a jetty break, fairly exposed, and this northeast swell is right on the money. It’s not gonna be big, but it’ll be the cleanest we get in this whole forecast. It breaks fairly consistently, so there might be a few rides to be had on a longboard. Just don’t expect any stand-up barrels.
Keep your chin up, it won't stay like this forever. Forecasts change, so stay tuned.
Rusty.
