The Lowdown
Alright, folks, let’s look at what’s coming up for Indian River (Southside). Don’t get too hyped just yet—this is a long-range look and conditions are looking pretty flat through the first week.
We’ve got a solid stretch of nothing happening from Monday the 10th right through to Tuesday the 18th. Tiny waves, poor conditions, and hardly any energy pushing through. The swell stays weak and small, mostly around 0.6ft to 2ft, with periods mostly under 7 seconds. Not worth paddling out for. Winds flip around a bit, but it’s not enough to make this place work.
Finally, by Tuesday afternoon the 18th, we see a slight flicker. Swell picks up a touch to 1.3ft from the SE at 15 seconds and the wind goes glassy—that’s a rare combo for this spot. The energy climbs a bit into Wednesday the 19th with 2ft from the ESE at 12 seconds, but the wind is only clean in the morning. It’s still tiny, but there might be a few fun little ones if you’re patient.
Things get a bit more interesting by Saturday the 22nd. Swell pushes to 4.3ft from the E at 7 seconds, but the wind is cross-onshore and makes it choppy. Sunday the 23rd cleans up with offshore winds, but the swell drops back under 3ft. Still, not the kind of waves to get the heart racing.
The standout? If you’re desperate, Tuesday afternoon the 18th gives you the cleanest, glassiest window all forecast period—but you’ll be hunting for knee-high nuggets.
Overall, Indian River is in a quiet spell. The second week shows a little more push, but the wind keeps working against us. Keep an eye on it, but don’t plan your week around it.
