The Lowdown
Alright, Rusty here, let’s break this down. First few days are a bit flat and messy, so don’t rush.
The first halfway decent surf shows up on the morning of Tuesday, 15 September at Tramandai Pier (Platforma). We’ve got a clean 3ft swell from the south, with a 10-second period. The wind is blowing cross-off, so it’ll be smooth. The combined energy is moderate at 326. It’s not big, but it’s rideable.
The real standout is the morning of Wednesday, 16 September. The swell comes up to 5ft from the south, still with an 8-second period. The wind stays cross-offshore, keeping it clean. Energy jumps to 578. That’s the best wave you’ll see in this 16-day stretch. Good for intermediates.
Then the wind turns nasty from Thursday, 17 September. Strong onshore winds from the northeast blow in, ruining the surf for most of the following week. There’s a lumpy 8ft wave on Saturday, 19 September, but with 18 mph onshore wind, it’s choppy and ugly. More of a kite session.
We get a clean spell on the morning of Monday, 22 September. A 6ft swell from the east-northeast with a light cross-off wind. Energy is 490. It’s fun, but not a standout.
The last week is mostly poor with onshore wind. One more clean window on the morning of Thursday, 24 September: 5ft from the east with a light offshore wind from the west. Energy is 422. If you can make it, it’ll be glassy.
Bottom line: Wednesday morning, 16 September, is your shot. Clean 5ft south swell with cross-off wind. Don’t sleep on it.
Rusty.
