The Lowdown
Rusty here. Let's talk about the surf outlook for this part of the coast, centered on Barra da Lagoa.
Honestly, we’re looking at a long, dry spell. For the next 13 days or so, there’s not a whole lot to get the heart pumping. The water's about 63°, which is a touch cooler than average for this time of year, so you'll want the rubber.
The one true highlight in this whole 16-day window is Thursday, August 7th. That morning we’ve got a clean 3ft swell from the SE, running at 10 seconds, and the wind is going to be totally glassy. It’s going to be clean as a whistle. The wave energy is moderate at 269, and while it’s not big, the conditions should be spot on. Save your energy for that Thursday morning.
There’s a small chance on the 5th and 6th of August with slightly bigger swell – around 4ft to 4ft from the SE with a longer 12-second period (384-396 energy) – but the wind is all wrong. It’ll be cross-shore and cross-onshore, making it a choppy mess. That longer period means better shape, but it’ll be a fight. Hard pass unless you’re really keen.
For the rest of the period, it’s flat or blown out. A few days have clean, glassy conditions but with almost no swell (0.3ft to 2ft). This setup is honestly looking better for a kite session than a paddle. Just be patient and wait for that Thursday the 7th.
Rusty.
