The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Foz do Lizandro.
Right off the bat, I gotta be straight with you – this is a tough stretch. The river mouth at Foz do Lizandro is looking at a long, quiet spell. For the first week and a half, we're talking about hardly any push. The swell energy is just a whisper, and the winds are mostly cross or cross-on, which is going to keep things messy. There's a long gap here with basically nothing rideable, day after day.
The water temp is sitting around 70°, which is bang on average for this time of year, so no need to dig out the steamer just yet.
Now, things do finally start to stir around Wednesday the 27th of August. The early morning is our real standout. We've got a clean 4ft swell pushing out of the NW, with a period of 10 seconds, so a bit of energy behind it. The best part? Glassy conditions. That's a huge plus – it'll be as clean as it gets around here. The combined energy is moderate (343). This is the window to paddle out if you can. The swell direction is coming from the NW, which isn't the absolute optimum SW, but it'll wrap in okay.
However, hold your horses for the 29th of August. Saturday morning is looking at a solid 8ft swell from the WNW, with a period of 12 seconds and a massive combined energy of 1425. That's a lot of water moving. Problem is, it's predicted to be too big for this break, especially with a cross-on wind. That's expert territory at best, and likely a washing machine. The afternoon is onshore and just as messy.
So, to sum it up: there's a lot of flat and poor conditions to sit through, but if you're patient, the morning of the 27th of August offers a clean, glassy session with some fun waves. The 29th brings real size, but it's going to be a battle.
Stay patient, stay stoked.
Rusty.
