The Lowdown

Alright, let’s break down the next couple of weeks.

We got a slow start here at Foz do Lizandro (river mouth). The water is sitting at 65°F, which is much colder than normal for this time of year – that anomaly of -4°F is hard to ignore, it’ll feel proper chilly out there. Things start off pretty average on Saturday the 12th with a tiny 2ft swell from the WNW, period around 10 seconds, and combined energy is weak at 68. The wind is cross-off in the morning which keeps it clean, but the afternoon turns cross-on and choppy. Not worth rushing out for.

Sunday the 13th is where it gets interesting. A new 3ft NW groundswell rolls in with a 13-second period – that’s decent period, giving the waves a bit of push and shape. Combined energy jumps to 330 – moderate, but better. The morning is clean with light offshore from the SSE. This is the first real standout. The river mouth setup should handle that longer period nicely, giving some lined-up waves. Keep in mind it’s a beginner-friendly break and sometimes crowded.

Monday morning the 14th is another high point – 3ft NW swell, 11-second period, combined energy of 288 and total glass. Zero wind, so it’s flat as a mirror, absolutely clean. That’s the kind of morning you wake up early for. The afternoon goes cross-on though, so make the most of the dawn patrol.

After Monday things go a bit downhill. Tuesday the 15th and Wednesday the 16th are mostly messy, with strong cross-shore winds and lumpy conditions or no swell at all. There’s a big gap from Tuesday through until the following Monday – no quality windows in that stretch.

Come Saturday the 19th, there’s a 5ft NW swell with 14-second period – combined energy is a beefy 1042, so there’s real power in the water. But the wind is a moderate cross-shore, creating cross-chop. It’s rideable but not perfect. That size is getting up there – fine for experienced surfers, beginners might find it a handful.

Then Monday the 21st afternoon you get a 7ft NW swell (14-second period) with combined energy at 1597. The file says the swell is predicted to be too big for this break, and that rings true. That’s expert only territory at the river mouth, so unless you’re solid, sit this one out.

Tuesday the 22nd morning is even bigger – 8ft NW swell (13-second period), combined energy at 2005. That’s a lot of water moving. For the experienced crew only, and even then, it’s likely closing out or washing through the river mouth. The wind is cross-off though, so the surface will be clean – just an absolute beast.

The rest of the window into the second week is small, messy or onshore – mostly 0.3ft swells and choppy conditions, not worth the paddle. No real standouts out there.

If you’ve got a kite, those windy, choppy days in the middle might be more your thing than a paddle board.
