The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for this stretch of coast.
Straight up, it’s a rough start. We’re looking at a gap of several days with nothing worth paddling out for, all the way through to Saturday the 13th of September. The early stuff is plagued by poor conditions, strong cross-shore winds and weak, short-period slop. You wouldn’t bother.
The first real glimmer comes Sunday morning, the 13th. Foz do Lizandro turns it on. Glassy conditions, not a breath of wind, with a clean 3ft NW swell running at a nice 13-second period. That’s proper groundswell energy – you can feel the pulse in the moderate combined energy (330). For a river break, that long period can be a real treat, drawing lines in and offering some shape. This is your standout. The water is sitting at 65°, which is 4° colder than normal for this time of year – that’s noticeably chilly, so don’t forget a hood if you’ve got one.
The Sunday afternoon session gets messy with onshore wind, so make the most of that glassy morning.
After that, Monday the 14th is okay early with light cross-shore wind and a 3ft NW swell (288 combined energy), but it’s nothing to write home about. The rest of the week goes downhill with building north winds and messy cross-chop.
The next proper highlight doesn’t roll in until Saturday the 19th of September. Again, Foz do Lizandro early morning with a light cross-off breeze and a clean 4ft NW swell (235 combined energy). It’s a fun size, and the crowd profile says “sometimes” – so you might have company, but it won’t be a zoo.
Then Sunday the 20th and Monday the 21st mornings both look promising. Sunday has a slight SE breeze, cross-off, with a 4ft NW swell (328 combined energy). Monday is glassy again, with a light WNW breeze and the same 4ft NW swell (245 combined energy). Those are solid, clean sessions for a river break.
Later in the window, around Tuesday the 22nd, the swell picks up to 6ft from the NW with a 12-second period and combined energy hitting 918 – that’s strong energy. But the wind is a moderate cross-shore, and it’s messy. That size and chop is more interesting for kite surfing than a clean paddle session.
So, to sum it up: the best on offer is Sunday morning the 13th, with glassy conditions and a long-period groundswell. Second best is the string of clean mornings from Saturday the 19th through Monday the 21st. Everything else is either blown out or too small.
Stay stoked,
Rusty
