The Lowdown
Alright, Rusty here. Let's get into it.
Well, I gotta be straight with you. We’re looking at a pretty grim stretch ahead for Indian River (Southside). There’s not a single standout session in this whole 16-day window, which is a real bummer. The forecast is basically a long, flat spell with nothing worth paddling out for. The first record kicks off on Tuesday the 8th of September, and from there, it’s a long, dry run.
The water’s sitting at 77° right now, which is much warmer than normal for this time of year, but that’s about the only headline here.
For the first week, from the 8th through the 14th, the swell is tiny. We’re talking ankle-biters between 0.7 ft and 3 ft at best, with wind mostly onshore or cross, and the energy is weak (45 at best early on). Even on the 13th and 14th, when a bit more energy shows up (104, 48), the swell direction is SE with a short, choppy period, and the wind is cross-onshore. It’s just messy and small.
The second week doesn’t offer any hope either. We see the biggest numbers on the 20th and 21st of September, with swell heights hitting 4 ft and energy climbing to 194, but the wind is straight onshore from the ENE or cross-onshore. That’ll just be a blown-out, lumpy mess at this beach/jetty setup. The period is short (6-8 seconds), so the waves will be weak and crumbly. Honestly, with that wind and swell combo, this spot looks more interesting for kite surfing than paddle surfing.
For a brief moment on the afternoon of the 16th, we get a glassy window with light wind, but the swell is a pathetic 2 ft with no energy (28). Just not enough to ride.
So, to sum it up: there’s nothing on offer. A blank run like this is pretty normal for the area when the trade winds set in and the swell windows shut down. Better luck next time.
Rusty.
