Indian River (Southside) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Indian River (Southside).

To be straight with you, the start of this run is a quiet one. We’re looking at a long stretch of tiny, weak surf with barely enough energy to get excited about. From Sunday the 23rd right through to the end of August, the swell is hanging around the 0.7ft to 1ft mark with periods dropping as low as 5 seconds. The combined wave energy is sitting in the double digits (29–51 range), which tells you it’s barely moving. Winds are a mix of cross, on, and offshore, but with next to no swell, it doesn’t matter much. The first real flicker of hope shows up on Friday morning, the 28th, when we see 2ft ESE swell at 8 seconds and clean conditions with a cross-offshore breeze, but the report says “surfable but very ordinary.” It’s not worth paddling out for.

We then enter September with a building trend, but conditions are messy. Tuesday the 1st and Wednesday the 2nd see the energy jump into the three digits (131–143) with 1ft to 2ft swell, but the wind is onshore or cross-onshore, making it choppy. Still, not what you’d call a session.

Now, here’s where it gets interesting. Thursday the 3rd of September is the standout. Come Thursday morning, we’ve got a clean 3ft ESE groundswell (12 seconds) with a gentle offshore wind from the west. The combined wave energy hits 239 – moderate, but building. It gets even better by Thursday afternoon: the swell pushes to 3ft ESE, period stretches to 13 seconds, and the energy rockets to 598. The wind turns cross-offshore from the northwest, and the call is “very good surf conditions.” For an advanced spot like Indian River (Southside) that’s fairly consistent and exposed to that SSE direction, this is the pick. The water’s sitting at a balmy 77°F, which is about a touch warmer than normal for this time of year, so you won’t need a spring suit. The offshore winds will keep it clean, and that longer-period groundswell should offer some proper shape, though at a beach/jetty setup it might break a little straight. Still, it’s the best on offer.

Friday the 4th holds similar 3ft ESE swell but with stronger cross-offshore winds (15–16 mph). It’s still clean, but the energy drops a touch and the forecast dials back to “marginal.” Saturday the 5th throws in a size jump: 6ft ENE swell in the morning, but it’s cross-onshore. The real magic is Saturday afternoon – glassy conditions with 5ft ENE swell and 519 combined energy. That’s a great session if you can handle the size, but because it’s over 5ft, beginners might find it a handful. That ENE direction isn’t the optimum SSE direction this spot loves, so it may not line up perfectly.

The rest of the run into the second week sees some decent swell pulses – 4ft to 5ft on Monday the 7th with offshore winds – but the periods get short (6 seconds on Monday afternoon) and the energy drops. The window of truly good surf is really the 3rd and 5th of September. After that, it’s clean but not as punchy.

Bottom line: wait for Thursday the 3rd and Saturday the 5th. Thursday looks cleaner and more lined up with the swell direction, but Saturday brings size and glass. If you’re advanced and want the best, Thursday afternoon is the call. Crowds are often a thing here, so expect company.

Stay stoked,
Rusty
