The Lowdown
Alright, this is Rusty. Let’s look at what’s happening with the surf for the next two weeks.
To be straight with you, this stretch starts off really quiet for Indian River (Southside). There’s just not much going on for the first week and a half. The first time we see anything even worth mentioning is Sunday morning, August 23rd. That’s a solid 12-day gap of nothing but tiny, poor surf with messy wind. You’re looking at close to two weeks of flat-ish, choppy conditions before anything clicks.
So, what’s on offer? There’s a tiny window that’s the best of a very average bunch.
The standout session is Sunday morning, August 23rd. We get a clean, 2ft swell from the SSE with a light offshore wind out of the W. It’s small, but it’ll be the cleanest surf of the whole period. This is a real beginner-friendly size, too. The water is a touch warmer than normal, sitting at 78°. The wave energy is weak (52), but with the clean wind, it’s your best shot at getting a few workable runners on the bank.
The second option is Monday morning, August 24th. Same deal: a small 2ft swell from the SSE with light, clean wind. It’s very ordinary, but there will be a wave. Just don’t expect any power. The combined energy is still weak (50).
Honestly, if you’re looking for proper swell, this forecast is a dud. There’s one brief pocket of clean, small waves right at the end. For the rest of the 16 days, it’s a waiting game.
Stay patient. Rusty out.
