The Lowdown
Alright folks, Rusty here. Let's be honest, looking at this 16-day window for Foz do Lizandro, it's a rough one. We’ve got a long stretch of nothing where the surf just isn't worth paddling out for. The wind is mostly from the north or north-northwest, and it's coming in cross or cross-onshore, just chopping everything up. From Tuesday the 4th of August all the way through until Saturday the 16th of August, it's a write-off. The swell is tiny, the wind is messy, and every single report is waving us off. It’s a solid 12 days of flat, blown-out conditions.
Now, after that long wait, we finally get a bit of a pulse. On Sunday morning, the 16th of August, things start to look a little different. We’ve got a 5 ft swell rolling in from the NW with a period of 8 seconds. The combined energy hits 262 (moderate), which is the most we’ve seen in the whole forecast. The wind is a light N cross-shore at 9 mph, so it’s *almost* clean. But be warned, the water temp is sitting at 67°, which is about 1° cooler than usual for this time of year – nothing crazy, just a little on the fresh side. This is still a marginal call, and it's only for the morning. By the afternoon the wind picks up and the swell gets bigger and messier, hitting 7 ft. That size is getting into expert-only territory, and with the wind turning cross-onshore, it’ll be a sloppy, lumpy mess.
The standouts? Honestly, there are none. The only day that even gets a sniff of a recommendation is the morning of Sunday the 16th. If you’re desperate, that’s your window. But don’t expect much. The rest of the time, you’re better off finding something else to do.
Rusty.
