The Lowdown

Alright folks, Rusty here. Let’s get into it for Barra da Lagoa.

First up, I’m gonna be straight with you – the next 16 days are a real mixed bag, and honestly, there’s a lot of filler to wade through. The water temp is sitting at 66°, which is dead average for this time of year, so no surprises there.

The first proper standout on the calendar is Wednesday morning, the 2nd of September. The swell jumps up to a solid 7ft out of the SSE, with a period of 10 seconds. That’s a decent amount of energy (964). Pair that with a gentle cross-off breeze from the South, and you’re looking at some clean, punchy waves. This is the best on offer for the whole window, no question. That 7ft is pushing into expert territory, though, so it’s not for the beginners. The wind is light, so it’ll be super clean.

After that, things get a bit messy. Thursday the 3rd sees a smaller swell, but the wind is swinging cross and cross-on, making it choppy. Friday the 4th drops right down to 3ft with weak energy (159), and the weekend is basically flat as a pancake – 1ft and 1.0ft with barely any energy (37 and 16). It’s a real dead zone for a few days there.

Now, keep an eye on Tuesday morning, the 8th of September. We get another pulse of 6ft from the SSE with moderate energy (734). It’s a bit of a gamble, with a "marginal" tag on it, but with a gentle cross-off breeze, it could clean up nicely. That’s your second-best bet in the whole run.

The 9th of September, Wednesday morning, is a real tease. Only 4ft, but the wind goes glassy, dead calm. The conditions will be perfect, but the swell is just too small to get excited about.

After that, we’re back into a long stretch of very poor conditions. From the 10th right through to the 16th, there’s a lot of nothing, with wind howling onshore or just tiny, weak waves. There is a small bump on the 14th with a 8ft swell, but it’s got a short period of 7 seconds and a cross-shore wind, so it’s going to be a messy, lumpy mess. That one’s more for the kitesurfers, honestly.

So, to wrap it up: your clear window is the 2nd of September morning. That’s your day. The 8th of September is worth a look if you’re desperate. The rest of the 16 days? A lot of waiting for the next proper swell.

Rusty.

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.
