The Lowdown
Alright, Rusty here.
Alright, let’s be straight with you – this 16-day window is a tough stretch for Praia da Barra. We’re looking at a lot of chop, a lot of cross-shore wind, and not many clean windows. There’s a real gap of surf worth paddling out for, so don’t be in a rush.
Let’s start with the pattern. Most days, we’ve got a moderate to fresh breeze out of the NNW, and that’s just putting a chop on everything. The swell energy through the first week and into the second is mostly in the moderate range (400-500 combined energy), but the quality just isn't there. The best windows are few and far between.
Alright, the one standout that actually looks like a proper session is on Monday, 21st September, in the morning. We get a clean, offshore wind from the ENE at just 6 mph, and a solid NW groundswell moving in at 5 ft with an 11-second period. The combined energy jumps to 580, which has a bit of grunt, and that offshore breeze means it’ll be clean. This is your best bet in the whole run. The swell is manageable for most intermediates, and that longer period will push in some proper lines across this sandbar. Crowds can show up here sometimes, so get in early.
Before that, there are a couple of other small windows. On Thursday, 10th September, the morning goes glassy with a NNW swell of only 3 ft and an 11-second period. The combined energy is moderate at 422, and combined with no wind at all, it’ll be clean. It’s a small wave day, but glassy is glassy. The water temp is sitting at 68°, which is about average for this time of year, nothing unusual there.
Then on Sunday, 13th September, the morning is completely calm and glassy, with a 3 ft swell from the NW, but the period is a very long 12 seconds. The energy is moderate (450), but swell that long can sometimes straighten out on a sandbar. Worth a look, but don’t expect the best shape.
After that, the gap opens up again. For the rest of the window, it’s mostly wonky cross-shore winds and lumpy conditions. That Monday morning 21st September is truly the highlight, and if the forecast holds, it’s your day.
Signing off, Rusty.
