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.

Information about the Barra da Lagoa Surf forecast
The above surf forecast table for Barra da Lagoa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barra da Lagoa can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Barra da Lagoa may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
