The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what Foz do Lizandro has got cooking for us over the next couple of weeks.
Right off the bat, I gotta be straight with you: this forecast is a bit of a heartbreaker. For the first week and a half, it’s a whole lot of nothing. We’ve got onshore and cross-shore winds from the north blowing like crazy, and while there’s a bit of swell around, it’s all getting chopped to pieces. The water temp is sitting at a pretty standard 68°F, about average for this time of year, but you won't be feeling it 'cause you won't be in the water.
We’re looking at a real dry spell from now all the way through to the 12th of September. Sure, there's a little bump of energy on Sunday the 8th with a 4ft swell, but the wind is just ruining it. There’s a moment on the morning of Saturday the 12th where it goes clean with a light offshore breeze, but the swell is a tiny 1ft. Not enough to get excited about.
The first real glimmer of hope comes on the morning of Sunday the 13th. This is where things get interesting. We’ve got a solid 3ft groundswell from the NW with a long 13-second period, and the wind? Glassy. Dead flat. It’s going to be clean as a whistle. The energy is moderate at 392, so it’s got some push behind it. This is the standout of the first week. Get on it if you can. The afternoon gets a bit more questionable as the wind swings onshore, so make it a dawn patrol mission.
Now, the second week looks a little more promising for swell size, but the wind is a constant problem. We get a bigger pulse of swell around the 16th and 17th with waves pushing 6ft to 7ft from the NW, but it’s accompanied by strong, messy cross-shore winds. That kind of power (combined energy around 900-967) is decent, but the conditions are just too lumpy for a good paddle. Honestly, that setup looks more interesting for kite surfing than a clean surf session.
The real highlight of the entire forecast is the morning of Monday the 21st of September. We’ve got a clean 5ft swell from the NW with an 11-second period and glassy conditions. The combined energy is a solid 566. The wind is a slight air from the south, making for a glassy surface. That’s about as good as it gets. The swell is a bit too much for beginners at 5ft, but for the rest of us, this is the session to aim for. Just be aware that Foz do Lizandro can get crowded, so you might have some company.
So, in short: wait it out. The 13th is your early bet for clean, small waves. The 21st is the big one on the horizon, but it's a long way off, so don't hold your breath just yet. The rest is a write-off unless you’ve got a kite.
Rusty.
