The Lowdown
Alright, this is Rusty, and I'm looking at the stretch ahead for Barra do Sul. Let's be straight with each other – this isn't gonna be one for the photo albums. We've got a long, dry run of small, messy energy on the cards, with a couple of faint glimmers of hope way down the line.
The water is sitting at 66°F, which is pretty much what you'd expect for this time of year, so no surprises there.
The first week and a half is a grind, honestly. From the start of the forecast right through to the 4th of August, we're looking at small swell, mostly in the 2 ft to 3 ft range with periods under 10 seconds. The energy is weak, barely cracking 100 in the combined reading. Most mornings will start glassy, but the swell is just too weak to do anything with. Afternoons get chopped up by onshore breezes. You could paddle out for a sanity check, but don't expect much.
The first real nod we get is on the morning of Thursday, the 6th of August. The wind goes glassy from the WNW, and we get a pulse of long-period groundswell from the SE at 3 ft with a period of 12 seconds. The combined energy kicks up to 293, which is solid. That long period means the waves will have some shape and push, but this is a beach break setup, so it might get a bit straight and fat. Still, with zero wind and a bit of energy, that’s the best morning of the whole outlook.
Then, after a dip, the morning of Saturday, the 8th of August offers another chance. We’ve got a light offshore breeze from the NW, glassy conditions, and a 3 ft east swell ticking over with a period of 8 seconds. The energy reads 211, so it's moderate. It won't be perfect, but it'll be clean and rideable.
If I'm being honest, the standout is that Thursday morning, the 6th. That's the one to circle on the calendar for a dawn session. The Saturday after that is the backup. The rest? It’s a lot of waiting for not much reward. A blank run like this is pretty normal for the area when the ocean switches off.
Keep an eye on the forecasts closer to those dates. Things can change, but for now, it's a waiting game.
