The Lowdown
Alright, let’s break down what’s comin’ for the next couple of weeks at Foz do Lizandro, a river mouth spot that’s exposed to the swell. It’s a beginner-friendly break, fairly consistent, and the ideal swell direction is from the southwest, though we’re mostly seein’ north-west and west-north-west swells. Water temp is about 69°, which is pretty normal for this time of year.
First off, we got a real quiet stretch. From Wednesday afternoon all the way through to Sunday the 13th, it’s mostly a bust. Swell is tiny, wind is messy, and the scores are all zeros. There’s a few glassy moments on Friday and Saturday mornings (4th and 5th), with waves around 2ft to 3ft from the west-north-west, but the energy is weak and the conditions are “very ordinary.” Not worth the effort. Saturday afternoon sees a spike in energy from a 15-second period north-west swell, but it’s cross-on wind and only about 2ft – just a tease. So you’re lookin’ at about a ten-day gap of nothin’ really worth paddlin’ for until Monday the 14th.
Now, Monday morning, 14th of September – that’s the one to circle. We get a solid 6ft north-west swell with a long 14-second period, and it’s glassy, dead calm. The energy is pumpin’, and the call is “excellent surf conditions for experienced surfers.” This is a groundswell with some real power. The direction is north-west, not the ideal south-west, but the quality is too good to pass up. It’s over 5ft and under 8ft, so it’s for the more experienced crowd – beginners are better off sittin’ this one out. The long period at a river mouth can mean the waves set up nicely, but those sets will have some weight to ’em. That’s the best of the whole run.
Tuesday the 15th still has some size – about 6ft in the morning, north-west, 13-second period – but the wind is cross-shore and it’s lumpy. It’s a marginal call, and the afternoon turns into a fresh cross-shore mess. After that, from the 16th onward, it’s back to small, weak, and windy. The last week of the outlook is just more of the same – tiny waves and strong, messy winds.
So, if you’re waitin’ for a wave, you gotta be patient. There’s no real surf until Monday the 14th. That morning is your best shot for clean, powerful waves. Don’t miss it.
