The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for our local stretch.
Right off the bat, the water is sitting at 66°, which is nearly two degrees colder than usual for this time of year, so you're gonna feel that bite more than you expect. The surf, well, it's a bit of a slow burn. We're looking at a pretty flat start to the week. There's a small pulse Monday morning at Foz do Lizandro with clean 3ft waves from the NW, but it's weak energy (306) and the afternoon gets messy. After that, we hit a proper lull. From Monday afternoon all the way through to the morning of Sunday the 21st, it's basically flat or junk. There's no real swell to speak of, just tiny leftovers with cross-shore winds that are only good for tanning on the beach. That's a solid five-day gap with nothing worth paddling out for.
Now, the real story starts on Monday the 21st. That's the standout. Monday morning is where it's at. We've got a proper 5ft groundswell from the NW, packing a solid punch with 827 energy, and it's a long-period 13-second swell. But the magic is the wind – a light offshore breeze from the ESE, making it clean. This is the session to circle on your calendar. The river mouth setup at Foz do Lizandro should handle that long-period energy well, offering up some proper shape. The afternoon gets onshore and messy, so hit it early.
The quality hangs in there for Tuesday the 22nd morning too – a clean 4ft NW swell with glassy conditions. Still very good, just a step down from Monday's peak. After that, the week tails off again into smaller, wind-affected surf until we get another shot on Friday the 25th and Saturday the 26th. Those mornings offer clean 4ft and 4ft NW swells respectively with offshore winds, so they are good, solid options but not the standouts.
Finally, keep an eye on Sunday the 27th. That morning sees a big jump in energy with a 6ft NW swell (1970 energy), but it's got a bit of cross-shore wind. The afternoon, though, is a monster. 8ft from the WNW, but the report says it's likely too big for this break. That’s expert territory only, and the winds are a bit messy. The swell energy is massive (1841), so if you're a seasoned charger, it might be your wave, but for most of us, Monday the 21st is the clear winner.
So, to keep it simple: the next week is quiet. The real gem is the morning of Monday the 21st. Get after it.
