The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
To be straight with you, this is a tough stretch. We’re lookin’ at Sebastian Inlet-Third Peak (beach/jetty) and honestly, for the first week and a half, there’s damn near nothin’ worth paddling out for. There’s a real dry spell from now until around the 12th of September, with a bunch of days where the swell is tiny and the wind is mostly junk. The water temp is sittin’ at a warm 83°, which is pretty much average for this time of year, so no surprises there.
The first proper little blip of hope shows up on Saturday, 12th September in the afternoon. Swell bumps up to 4ft from the NE, but it’s a short period windswell at just 6 seconds, and the wind is a moderate cross-shore from the ESE at 12 mph. The combined energy is moderate (132), but conditions are already described as poor with a cross-chop. Not a classic, and it’s messy.
The real standout, the only time I’d really get excited, is the morning of Sunday, 13th September. We’ve got 5ft of swell from the ENE, still short period at 6 seconds, but the wind goes glassy – dead calm from the north at 3 mph. That’s a window of clean conditions. The combined energy is strong (178), but the wave quality is still just “ordinary.” It’s not perfect, but it’s the best we’ll see. That 5ft is getting up there for beginners, so it’s more for the intermediate crew.
After that morning, it falls apart again. The afternoon of the 13th gets onshore wind, and the following week is a write-off with onshore winds and small, weak swell. The energy drops right back down to weak levels (under 100). The 19th of September has a fresh cross-shore from the ESE, but it’s blown out and lumpy.
So, bottom line: keep your eyes on Sunday morning, 13th September. That’s your one clean shot. The rest of the 16-day window is mostly a flat, blown-out mess. It’s a lean run, but it doesn’t stay poor forever, so keep an eye on the charts.
Rusty.
