The Lowdown

Alright, let’s get this out there. This is for the whole stretch ahead.

Look, I’ve studied the forecast for Barra da Lagoa over the next couple of weeks, and I have to be straight with you—it’s nearly all frustrated paddling. This is the kind of run where you save your wax. We’ve got a solid 16-day window, but there’s almost nothing to get excited about. There are massive gaps where the surf just isn’t on. For instance, from the start of the period right through the first week and a half, the conditions are consistently labelled "poor". The first proper chance at anything doesn’t show up until the morning of Monday the 21st, and even then it’s just “surfable but very ordinary.”

The only real standout that deserves a mention lands on Friday the 25th. The morning session at Barra da Lagoa (Santa Catarina) shows a 6 ft swell from the SSE, with a long period of 15 seconds. That’s got some proper groundswell energy behind it, clocking in with strong wave energy (1442). The wind is a moderate cross-offshore, so it’ll be fairly clean. But here’s the thing—that’s a solid 6 ft with long-period swell, which can get a bit unruly on a beach break. It might be better suited to the points or reefs if you can find them, because long-period swells like that can close out on the sand. That said, for a surfer with some experience, it’s the best we’ve got. The water is about average for the time of year, sitting at 64 °F, which is a touch colder than normal.

Outside of that, the Thursday afternoon the 24th has a tiny pulse, and the 26th and 27th show some waist-high leftovers, but the wind is messy and cross-onshore, so expect chop.

Honestly, this is a tough outlook. If you’re a kite surfer, the moderate breeze days with cross-shore winds might offer something, but for a paddle surfer, wait it out. The second week looks particularly bleak with more gaps and no quality.

Stay patient, and keep an eye on it—forecasts change.
