The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, I gotta be straight with you – these next couple of weeks are looking pretty grim for Foz do Lizandro. We’ve got a real dry spell on our hands. From now, all the way through to the morning of the 5th of September, it’s basically a write-off. There’s a few days in there with some size, but the conditions just aren’t coming together.
The first real glimmer of hope shows up on Friday morning, the 5th of September. Foz do Lizandro is a river mouth setup and it’s exposed to the swell. The water temp is sitting around 68°, which is pretty normal for this time of year, nothing unusual there. On that Friday morning, we’re looking at a clean 4ft of NW swell, with a period of 11 seconds (moderate energy of 565). The wind is absolutely glassy – completely off. That is a major positive, meaning you’ll get some clean, text-book lines. For a beginner-friendly spot like this, that is as good as it gets for the size. It’s a fairly consistent break, but the crowds can be around sometimes.
Saturday afternoon the 5th is a no-go, and Sunday morning the 6th has a bit of life. We’ve got 4ft of NW swell, 12-second period (energy of 392), and again, glassy conditions. It’s not huge, but it’ll be clean and fun again. But look, the rest of the window after that just falls back into the poor surf category with onshore winds and tiny waves. It’s really just those two windows on the 5th and 6th that are worth paddling out for. The rest? Forget it.
This is just one of those bleak spells. It happens. We go through these patches, and then the forecasts shift. It never stays this poor for long.
Stay patient, Rusty.
