The Lowdown
Alright, Rusty here. Let’s get into it.
To be straight up with you, this 16-day window for Indian River (Southside) is a tough stretch. There’s really nothing that’s gonna get the heart pumping. We’ve got a long, drawn-out run of small, weak surf and onshore or cross-shore winds that are just killing any chance of quality. The first proper chance of anything rideable doesn’t show up until Monday morning, August 3rd, and even then, it’s a mixed bag. From now through the weekend, you’re looking at flat to knee-high slop with cross-chop. Not worth paddling out.
The only period that even sniffs at being noteworthy is Monday the 3rd. The swell bumps up to 5 ft from the SSE, and the wind turns cross-off from the SSW. It’s clean, and the combined swell energy jumps to 264 – that’s moderate energy, a real spike compared to the rest of the forecast. The problem is, the guidance rates this break as advanced-only with fair consistency, and the wind is a fresh 18-22 mph. That’s a lot of breeze, even if it’s offshore. It’ll be lined up and a bit of a handful, but honestly, for a surfer who knows what they’re doing, it’s the only real window with any grunt. The swell period is short, though – only 8 seconds – so it’ll be a bit sectiony and won’t have that long, drawn-out wall.
After that, it’s back to the doldrums. Tuesday the 4th morning has a tiny improvement as the wind goes light offshore from the west, but the swell drops to 3 ft and the energy craters to 80. It’s surfable, but just barely. Then we get a whole lot of nothing: clean but tiny 2 ft to 3 ft days through to the end of the first week, all with cross-off winds, but the energy is feeble. The water temp on the 31st was 75°, which is dead normal for this time of year, so no surprises there.
To be honest, the entire run from the 5th of August through the 15th is a write-off. There’s one moment on the morning of the 11th where it goes glassy, but the swell is only 2 ft and the energy is 57. You might get a few ankle-biters. The break is a beach/jetty setup, and with these tiny, weak swells and mostly poor conditions, this looks more interesting for a longboard or a SUP than a high-performance shortboard. For the true standout? It’s gotta be Monday the 3rd. If you’re an advanced surfer and you can handle the wind, that’s your only real chance at a wave with some push. It’s not perfect, but it’s the best we’ve got.
Rusty.
