The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's on the menu for the next 16 days down at Barra do Sul.
It's a slow start. For the rest of this week and straight into the weekend, it’s looking pretty flat and messy. We've got a few days of small, weak, and choppy conditions with cross-onshore winds making a mess of things. The swell energy is weak, sitting between 109 and 207 for the combined energy, so don't get your hopes up.
Monday the 31st of August shows a glimmer of hope. The early session is still ordinary, but by late morning into the afternoon, the wind drops off and it goes glassy. We're looking at a small 3ft easterly swell with a bit more period, and combined energy hitting 137. It's not gonna blow you away, but it's rideable and clean.
Tuesday the 1st of September is much the same – small, clean, and glassy in the morning. The water temp is about average for the time of year.
Now, here's where it gets interesting. The real standout is Wednesday the 2nd of September. That morning is looking like the best of the whole run. We've got a clean 4ft swell from the southeast, a period of 11 seconds, and combined energy of 404 – that's a proper step up in juice. With glassy conditions and a slight air, this is the session to target.
Thursday the 3rd of September also has some potential early. Offshore wind from the west is cleaning up a 4ft SE swell (229 combined energy). It'll be clean and fun, but the winds turn nasty in the afternoon.
There’s a real quiet spell from Friday the 4th through to the 9th. The swell drops right off and the winds are all over the place. A few clean moments, but nothing worth paddling out for.
Then, another proper standout pops up on Thursday the 10th of September. We're looking at a solid 6ft easterly swell hitting (1010 combined energy). That's got power – a bit much for beginners, but for the experienced crew, it’s excellent. Light cross-offshore winds in the morning will keep it clean, and it glassed off in the afternoon.
Friday the 11th of September holds some nice leftovers – 4ft from the east, clean and offshore early, then glassy in the afternoon (406 and 328 combined energy). After that, it fades out and the cross-onshore winds return for the weekend.
So to wrap it up, set your alarms for the mornings of Wednesday the 2nd and Thursday the 10th of September. Those are the days to go. The rest of the month is mostly a write-off, but mark those dates.
Stay keen,
Rusty
