The Lowdown
Alright, Rusty here. Let's break down what Indian River (Southside) is offering up for the next couple weeks.
To be brutally honest, it’s looking like a long, flat spell. There’s a big gap of tiny, weak swell and poor conditions all the way until Thursday, September 17th. The first week and a half is basically a total loss for any real surf – the combined energy barely gets into double digits, staying under 100, and the biggest wave in that stretch is a 3ft one on Friday the 11th, but it’s from the north with a weak 5-second period, so it’s just gonna be a messy closeout. Don't bother.
The only real highlight comes on Thursday morning, the 17th. A little pulse of ESE swell pushes through at 2ft with a 9-second period, and the combined wave energy finally bumps up to 88. The wind is light and blowing cross-offshore from the SSW, keeping the surface clean. It’s not big, and it’s still pretty ordinary, but it’s the only window worth paddling out in the whole forecast. This is an advanced break, so you’ll want some experience to get the most out of these small, clean runners. The water temp is about average for the season.
After that, the 18th and 19th are back to small, choppy, or short-period slop. The 18th has clean conditions with NW winds, but the swell is only 2ft. The 19th sees a bump to 3ft, but the period crashes to 5 seconds and the wind cranks onshore, making it lumpy and messy. The 20th has a long-period 11-second ESE swell, but it’s only 1.0ft and gets trashed by fresh north winds. For a beach/jetty setup, that long period will just make it close out fast.
So, there’s a very narrow window on the morning of Thursday, the 17th for a few clean, small waves. The rest is a waiting game. Keep a eye on it, things can shift.
Rusty.
