The Lowdown
Alright, Rusty here. Let's chew the fat on what's coming down the pipe at Sebastian Inlet-Third Peak.
Gotta be honest, it's looking like a dead spell. Over this 16-day stretch, we're staring at a whole lot of nothing for a good long while. The first week and more are a total washout – tiny, weak, and wind-battered. Swell energy is barely registering, mostly hanging out in the double digits, so there's just no power in the water. And with the wind blowing onshore or cross-onshore most of the time, it's just going to be a choppy mess.
The only flicker of light comes way late. On the morning of Saturday, September 6th, the wind goes light out of the west-northwest – that's a cross-offshore breeze at 10 mph – and it cleans the place right up. The swell is still tiny, just 2 feet from the east with a short period, but for that one window, it'll be clean. Energy is weak at 25. If you're jonesing for a slide, you could probably find something on a longboard. The next morning, Monday, September 7th, also has that clean look from a light cross-offshore breeze, but the waves are even smaller.
For the most part, with the steady wind and flat water, this stretch looks more interesting for a kite surfer than someone with a paddle. There aren't any standouts in this forecast. It's a lean run, so don't hold your breath. Maybe keep a board handy for that Saturday the 6th morning if you're desperate.
Rusty.
