The Lowdown
Hey crew, Rusty here. Let’s get into this forecast. Gotta be honest, the outlook for the next couple weeks is a tough pill to swallow. We’re in for a long, quiet stretch.
Kicking off on Monday, September 7th, it’s not looking good. There’s some energy in the water (237), but we’ve got a risk of thunderstorms and a strong east wind blowing at 22 mph. The surf is a weak 3ft of short-period SW slop. Water temps are sitting right around 80°, which is pretty average for this time of year.
From Monday afternoon all the way through Monday the 14th, it’s a total desert. The swell dries up to nothing – most days showing waves under 3ft with weak energy readings. Tuesday the 8th actually shows a spike in energy (610), but a nasty cross-shore wind at 19 mph makes it a choppy, closed-out mess. That’s a hard pass, mate.
Even when the wind turns favorable, the waves are just too small. It’s a grim run, but for a spot that needs a big northwest groundswell to light up, this kind of dead spell is par for the course.
The only real standout, and I use the term loosely, is Tuesday the 22nd of September. The morning shows "surfable waves but very ordinary conditions". We’re looking at a 2ft swell from the NNW with a 10-second period, combined energy of (74), and a gentle east breeze at 9 mph keeping the surface glassy. It’s tiny, it’s weak, and the score is a 1 out of 10. After two weeks of garbage, it’s literally the only wave in town. Grab your log and some patience if you’re determined.
That’s the whole story. A whole lot of board storage time, with a whisper of hope right at the very end.
