The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Indian River (Southside) over the next couple of weeks.
Straight up, I’ve gotta be honest with you – this stretch is in a bit of a flat spell. The forecast shows a long dry run with no real surf to get excited about. We’re looking at tiny, weak swell and mostly poor conditions right through the end of August and into early September. You’ll see a few days with clean conditions, but the waves just aren’t there. This gap of no real surf stretches from now, Friday the 21st, all the way through to the end of the month.
The first hint of something that could be worth a look arrives on Tuesday, the 1st of September. The morning shows some clean conditions with a light offshore wind from the SW, and the swell is coming from the SSE at about 2ft. It’s still weak, with the combined swell energy sitting at only (51), so don’t expect much push. But the wind is clean, and it might be the best of a bad bunch. This break is advanced only, so it’s not for learners anyway.
The combined swell energy (117) picks up a little on Friday the 4th of September, with a 3ft swell from the S, but the cross-shore wind makes it choppy. The water temperature is about average for this time of year, nothing unusual.
Honestly, if you’re looking for something to surf, the window is tight and the waves are small. For paddle surfing, this isn’t the spot right now. A setup like this, with small, weak swell and some breeze, might actually be more interesting for a kite surfer.
