The Lowdown
G’day, Rusty here. Bit of a flat spell for the Indian River (Northside) this outlook. We’re looking at a long stretch with barely a ripple, but the back half of the 16-day window shows a bit of life.
The first real surf to speak of shows up Monday 17th, but even then it’s only a tiny 3ft of SSE swell with a clean morning—cross-off wind from the NNW at 6 mph keeps things tidy. Still, that’s 3ft, not exactly setting the world on fire. Combined swell energy is just 51 (weak), and the crowd is generally around. After that, it’s pretty much back to nothing through the rest of that week.
There’s a gap of a few days with no recommendations, but then we get a bit of a pulse around Wednesday 19th morning. The swell bumps to 3ft from the SE, with an 11-second period—that’s a proper little groundswell. Wind is cross-shore from the SSE at 9 mph, so it’s not perfect, but combined energy hits 233 (moderate), which is the best we’ll see for a while. The longer period will give the waves a bit more shape, though at a beach/jetty setup it might break a touch straight.
The real standout, if you can wait, is right at the end—Thursday 27th and Friday 28th of August. We’ve got a solid 5ft to 6ft of ENE swell rolling in, with a 6-7 second period. Combined energy jumps up to 290 and 296 (moderate-strong). The catch? Onshore wind from the E and ESE at 9-12 mph, so conditions will be choppy—this is more for the experienced crew who don’t mind a bit of texture. At that size and with onshore wind, this is not beginner-friendly; it’s pushing into expert territory.
Before that, there’s a tiny window Tuesday 18th afternoon with a 2ft SE groundswell and a 13-second period, energy 101 (moderate). Wind is onshore from the E at 6 mph, so it’s rideable but messy.
Water temp is sitting at a warm 78°F, which is a touch warmer than normal for this time of year—not hugely unusual, but nice.
One other thing: the rideable south-southeast swell on Monday 17th morning is the only time the wind direction really lines up clean. The longer-period SE swells later have that potential for shape, but the wind never fully cooperates.
Look, if you’re into kiting, those late-August days with 5ft+ E swell and onshore breeze might be your jam. For paddling, the best bet is the Wednesday 19th morning window if you want a chance at a clean line, or wait for the last few days of the month for size—but bring your tolerance for chop.
Rusty, signing off.
