The Lowdown
Alright, let’s break it down. I’ve got your Indian River (Southside) forecast right here.
First up, I gotta be straight with you – we’re looking at a pretty flat spell to kick things off. The first real surf recommendation doesn’t roll in until Tuesday the 25th, so that’s a solid gap of nearly a week with nothing to get excited about. The early days are all tiny slop, poor conditions, don’t even bother paddling out.
Tuesday the 25th afternoon we finally get a lifeline. The ESE swell pushes a 0.3m to 0.4m wave, period around 11 seconds. That’s about 1 to 1 feet. It’s small, sure, but we’ve got glassy conditions and the combined energy is sitting at a weak 69. That’s not going to blow you away, but for a spot that’s been dead, the clean glass is a massive positive. The water temp is about average for this time of year, so no surprises there. Indian River (Southside) is an advanced spot, so the tiny waves will still feel the tide, but if you’re desperate for a slide, Tuesday afternoon has your name on it.
Now, we cruise into deeper waters. The 27th and 28th of August? Forget about it for a normal surf. Strong cross-onshore winds, over 30 km/h (that’s about 18 to 19 mph), and combined energy hits 118 and 136 – that’s moderate energy. But it’s messy, lumpy, and the swell is all under 0.6m (about 2 feet). The setup here is a beach/jetty break, and with that much wind and chop, this looks more interesting for kite surfing than paddle surfing. Steer clear unless you’re on a foil.
The run into September tries to tidy up. On the 2nd of September, Wednesday morning, we see a clean, cross-off breeze from the WSW with a 0.3m ESE swell (about 1 foot). The period is 13 seconds and combined energy sits at 68. It’s surfable but very ordinary conditions. The 1-foot wave is barely a ripple, and even though it’s long-period, that makes it tougher to catch on a beach break.
Overall, there’s really only one standout here and it’s that Tuesday the 25th afternoon. It’s small, but the glassy clean conditions make it the best on offer by a long shot. Everything else in this 16-day window is either too windy, too small, or just plain messy.
