The Lowdown
Hey gang, Rusty here with the skinny on Tramandai Pier (Platforma) . It’s a bit of a mixed bag for the next couple weeks, but we’ve got a couple of sessions that are gonna be worth the paddle.
First off, don’t bother with Friday the 11th or Saturday the 12th. Rain, chop, and funky winds. Sunday the 13th morning goes glassy with a small 4ft wave from the southeast – it’s clean, but you’ll be working for it. Water temp is nothing out of the ordinary.
Monday and Tuesday are mostly a bust with strong onshore winds. Tuesday the 15th morning has offshore wind with a 4ft wave from the east-northeast – surfable and clean, but nothing to write home about.
Alright, here’s the one you need to get on: Wednesday the 16th morning. We’re looking at a solid 7ft of south swell with a combined energy reading of 920 – that’s proper moderate-to-strong stuff. Wind is a clean cross-offshore from the southwest, so it’s gonna be smooth. That’s the standout of the whole forecast. The swell direction from the south-southeast works well here. Keep an eye out – crowds are *sometimes* a thing.
Thursday the 17th throws a bigger 6ft swell from the south-southeast with a long 12-second period, and the combined energy is 1067 (strong energy). But the wind is a fresh onshore from the northeast, so it’ll be lumpy and hard to tame. Not a beginner wave at that size, and definitely more for experienced dudes with a bigger board.
After that, the swell drops back but stays clean in the mornings. Friday the 18th morning is a clean 3ft wave with an 11-second period – smooth and easy. The 20th and 21st of September also offer clean mornings with 6ft and 4ft waves from the east-northeast – not huge, but fun.
The last real highlight is Saturday the 26th of September morning. Glassy conditions again with a clean 5ft wave from the south-southeast and a 10-second period. Combined energy of 538 – moderate but clean. That’s a quality session if you can wait for it.
There are a few rough days in between with onshore winds, but the clean windows come through often enough. This spot can be frustrating, but when it lines up, you’ll have a smile on your face.
Catch ya in the water,
Rusty
