The Lowdown

Alright, let’s have a look at what’s on the cards for Barra do Sul. The next couple of days are pretty quiet – we’ve got some small, weak surf hanging around, nothing that’s really going to get the heart racing. The swell’s pretty inconsistent and the energy’s low, so it’ll be a bit of a wait before things start to pick up.

We’re looking at a stretch of small, weak waves through Wednesday and Thursday. The swell’s coming from the southeast, but it’s got no power behind it, around 3 ft with energy sitting at 104. Glassy conditions Wednesday morning will make it look clean, but it’s still pretty small. Nothing worth rushing out for.

Friday morning the swell switches a bit, more east-northeast, and it bumps up to around 4 ft. Energy jumps to 157, but it’s still a bit all over the place and the period’s short. Light rain around, but the wind is light and glassy, so if you’re desperate for a splash, it’ll be rideable, but not great.

Saturday looks like the first real push. The swell holds from the east-northeast, but the morning sees it jump to a solid 7 ft, and the energy really kicks in – we’re talking a big jump to 1002. That’s strong, powerful surf, but it’s still a short-period swell, and the wind is going to be cross-onshore. It’s got some size, but the conditions are going to be messy, so I’d hold off unless you’re keen on a challenge. The morning might be the best bet, but even then it’s going to be rough.

Then we’ve got a bit of a drop and a lull. Sunday, Monday, Tuesday all see the swell back down to around 3-4 ft, with energy dropping back to the 100-200 range. The wind swings more offshore in the mornings, so there will be some cleaner windows, but it’s still small and not particularly powerful. The consistency is there, but it’s just not doing much.

After that, there’s a real gap. Wednesday and Thursday of the following week – the surf fades right out. We’re down to under 3 ft, with the energy weak. It’s pretty much a dead spell.

Then, looking further out – next Friday, the 26th, there’s a bit of a pulse. Still small, around 3 ft, but it’s glassy and clean in the morning. Not a stand-out, but a bit of a tease.

The real notable period is the following Sunday, the 27th. The swell comes back from the southeast, around 4 ft, with the energy at 171. It’s not huge, but it’s got a bit more shape, and the morning glass is on. Slightly better quality there.

And then we get to the end of the window. Wednesday the 1st of October. The swell is still around 4 ft, but it’s coming from the southeast again, and the energy has picked up to 265. That’s a decent push, and with the glassy morning conditions, it’s looking like the pick of the whole run. It’s not going to be huge, but it looks clean and fun. The period is up at 10 seconds too, which helps give it a bit more push.

So, if you’re looking for the best of the bunch, that Wednesday morning at the start of October is where I’d be pointing you. It’s the standout for the whole forecast – clean, glassy, and a bit of energy behind it. Before that, it’s mostly small and messy, with a few windows of clean but weak surf. Worth being patient for that final one.
