The Lowdown
Alright, Rusty here again. Let’s break down the same outlook for Foz do Lizandro, now in feet and miles per hour.
It’s a bleak start. For the first several days you’re looking at messy cross-shore winds, choppy water, and barely a ripple. The combined swell energy is weak as hell. Don’t even think about a paddle. That gap lasts a good week.
The real action shows up on Sunday, September 13th. That morning you’ve got glassy conditions with a light NE breeze, and a solid groundswell comes from the NW at about 4–5 ft with a long 13-second period. Combined energy hits 559 (moderate). This is the best session of the whole 16-day run—clean, with proper wave shape. Crowds can show up here sometimes, so get in early.
Monday the 14th also delivers in the morning: glassy again, 5 ft of NW swell at 12 seconds, and combined energy of 639. That’s the biggest clean swell we see. From the afternoon on, the wind swings onshore and things go downhill fast.
Later in the forecast, Sunday the 20th morning offers a clean 2 ft NW swell, but it’s nothing to write home about. Most of the second week is back to poor, choppy, and low energy.
Short version: suffer through a dry week, then nail Sunday the 13th morning for the best waves of the lot. Monday morning also has potential if you can handle a little bigger surf. After that, it’s pretty much done.
Rusty.
