The Lowdown
Alright, Rusty here again. Let’s break this one down.
Honestly, this 16-day forecast for Foz do Lizandro is a tough one to swallow. We are looking at a real dry spell, with basically no good surf on offer. It’s a long stretch of small, messy, and mostly cross-shore to onshore junk. The first few weeks are just a write-off. If you were hoping for a run of waves, you’re out of luck.
The first week is dominated by moderate to fresh breezes from the north-northwest, which is cross-shore or cross-on for this exposed river mouth. That, plus a whole lot of tiny swell under 3 feet with short periods mostly under 10 seconds, means the ocean is going to be lumpy and choppy. The water temperature is about normal for the time of year, nothing special.
The absolute best you’re going to get is Sunday morning, August 4th. That morning we finally see some moderate wave energy (117), with a 3-foot swell from the west at 9 seconds. The wind will be a light cross-on from the northwest, so it won't be perfect, but that’s the cleanest window in the whole forecast. It’s your only real chance to snag a few, but keep your expectations low.
After that, the second week is flat-out depressing. We’re talking knee-high slop, and even a few days where there is literally zero energy in the water. There’s a long stretch of days that aren't worth even looking at the ocean.
Bottom line: Don't plan your life around this. For a spot that’s usually fairly consistent, this is a weird dead period. If you are desperate, Sunday morning, August 4th, is your one and only slim chance. Otherwise, save your energy.
