The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at Foz do Lizandro.
Right off the bat, I’ll be straight with you – this stretch of the forecast is a tough one. We’re looking at a long, dry spell of poor conditions that stretches from the end of August all the way through the first week of September. There’s just no good surf to be had for the first week and a half. The waves are small, and the wind is a constant cross-shore mess, mostly from the north at 19 mph, making for lumpy, bumpy, and choppy water. The wave energy is weak, barely getting into the moderate range at best, with readings like 77 (weak energy) and 104 (very weak energy). It’s a real bummer.
The one small glimmer of hope comes on the morning of Friday the 5th of September. The wind shifts to a cross-offshore from the northeast at 12 mph, which gives us a rare clean window. The swell is still tiny though, only 3 ft at 9 seconds from the WNW, with a combined energy of 104 (weak energy). It’s not breaking well, and the forecast still calls it poor surf. It’s a tease more than a session.
After that, we’re back into the same pattern. The wind stays onshore or cross-shore, mostly moderate to fresh, and the small swell sticks around. By Sunday the 7th of September, the swell picks up a little to 4 ft, but the wind is onshore, ruining any chance of shape. The whole run is a blank.
The only real standout – and I’m using that term loosely – is a marginal possibility on the morning of Saturday the 13th of September. We’ve got a stronger 3 ft swell from the west at 9 seconds, with a combined energy of 213 (moderate wave energy). The wind is light from the southwest at 3 mph, making it a cross-on breeze, but it’s light enough that the surface might be okay. The catch is the forecast only rates it as a 1 out of 10 – marginal at best. It’s the only day in the entire 16-day window that’s even worth a check, but be ready for questionable tide.
Outside of that, this is a long, quiet stretch. Foz do Lizandro is a river mouth, so it’s fairly consistent normally, but when the wind and swell align like this, it’s a dead zone. Because the swell is so small and the wind is almost always wrong, this setup looks more interesting for kite surfing than paddle surfing for most of this period.
Rusty.
