Barra da Lagoa Surf Forecast and Surf Report

Alright folks, it’s Rusty here, and I’ve got a mixed bag for you over the next couple of weeks. Let’s be straight up – the first week is a write-off, and we’re looking at a long, quiet stretch before things finally wake up. The real action is all the way out at the end of the 16-day window, so keep your powder dry.

We’re starting with Barra da Lagoa. This is the only spot on the radar, and it’s a beginner-friendly beach break that’s fairly consistent. The water’s sitting at 66°F, which is pretty much bang on average for this time of year – nothing weird going on there.

The first few days are a total bust. You’ve got onshore winds, choppy conditions, and barely a ripple. Saturday the 5th offers a tiny bit of hope with a 2ft swell from the SE and clean, cross-off winds, but the combined energy is weak (89) and the waves are just too small to get excited about. That’s your only real mention for the first week.

From Sunday the 6th right through to Wednesday the 16th, it’s a ghost town. There’s a long stretch of flat, clean conditions with no surf on offer. The odd bump shows up – like a 7ft SSE swell on Monday the 7th morning – but it’s paired with a short, crumbly 9-second period and the score is poor. Not worth paddling out for.

The real standout, and I mean the only standout, comes on Thursday the 17th of September. The afternoon sees a 3ft swell from the SSE, but the period is a massive 17 seconds – that’s proper groundswell energy. The combined energy is strong (629) and the wind is clean and cross-off. This is a long-period swell, which can be a bit tricky at a beach break – it might wrap a bit too straight – but with that light offshore wind, it’ll be clean and lined up. It’s the best call of the forecast.

Then Friday the 18th of September morning is the real big one. The swell jumps to 6ft from the SSE, with a 15-second period, and combined energy cranking up to 1581 – that’s strong, powerful stuff. The wind stays cross-off and clean. This is for experienced surfers only; it’s going to be a solid, heavy wave. The setup looks more like a proper groundswell session, so if you’re a confident paddler, get ready for some deep, clean lines.

So, to sum it up: the first week is a dud, the middle is flat, but the final two days of the forecast – Thursday 17th and Friday 18th of September – are the ones to circle. The 6ft SSE groundswell on Friday morning is the top pick, but it’s for the experts. The 3ft SSE on Thursday afternoon is a cleaner, more accessible option for the intermediate crowd. Keep an eye on it, but don’t get your hopes up until we’re closer to the date.

Rusty.
