The Lowdown
Alright, let’s have a look at what’s cookin’ for Indian River (Southside) over the next couple weeks. The swell window’s real tight here and we’re mostly starved for any kind of energy. Water temp is runnin’ 78°, which is a touch warmer than normal for this time of year, so the stingray shuffle is in full effect.
First real pulse that gets my attention comes Tuesday morning, 27th of August. We see a jump in swell height to 4 ft from the S with period at 7 seconds. That combined energy reads 224, which is moderate wave energy. The wind is cross-off from the NNW at 15 mph, keepin’ things clean. That’s the kind of morning you grab a step-up and hope for a few lined-up rights. The water temperature anomaly is a touch warmer than normal.
Thursday afternoon, 29th of August, the wind goes cross-off again from the NNW, cleanin’ up a small 1 ft SE swell. Not a standout but if you’re desperate, it’s a glassy session. Then we wait.
The real standout is Monday the 31st of August afternoon. The swell jumps to 6 ft from the ENE with a 7 second period. Combined energy blows out to 272, gettin’ into moderate territory. Wind is light cross-off from the WNW, so it’s clean. That’s the best on offer: not huge, not perfect, but surfable and tidy.
The following Tuesday, 1st of September morning, the swell hits 7 ft from the E with 8 seconds, and combined energy spikes to 571. That’s strong-to-very-strong energy, but the wind switches to a light cross, and the comment says marginal. Still, Tuesday afternoon brings a clean 6 ft ENE swell, also with 571 energy. That window is definitely the pick of the second week, though it’s a long way out so keep your fingers crossed.
After that, Wednesday the 2nd September gets choppy with onshore winds, so it’s a quick fade.
Honestly, overall, this break doesn’t have much on offer. The first pulse on the 27th and that 31st August-to-1st September window are your best shots. The rest is flat or messy. For an advanced spot with fair consistency, this is a lean spell. But if the swell arrives clean, you’ll have a few fun ones.
Stay hopeful. This is Rusty.
