The Lowdown
Right, folks, let’s have a look at the forecast for Barra da Lagoa.
First thing to say is, we’re in for a very quiet run. The first week and a half is pretty much a write-off with tiny, weak, and messy surf. The water is sitting at 66°F which is pretty much average for this time of year, no surprises there.
We’ve got a long gap here with nothing worth paddling out for from the start right through to the morning of Tuesday, August 11th. That morning, the 11th, we see a little bump of 4ft from the SSE, but it’s a short period windswell at just 6 seconds, and the combined energy is only 97 (weak). The wind is clean, cross-offshore, but the waves are ordinary. It’s not really a goer.
The next real glimmer appears on the morning of Friday, August 14th. Now, this is the standout. We’ve got a 4ft SSE swell with a lovely long period of 13 seconds – that’s proper groundswell energy. The combined energy jumps to 444 (moderate). The wind is light and cross-offshore, so expect clean faces. This is a real groundswell, so it’ll be better shaped and have more punch, but with that long period, it might wrap a bit straight at the beach break. Still, for a beginner spot, this is as good as it gets in the window. The morning of Saturday, August 15th is also a solid option. The swell holds at 5ft from the SSE, period drops slightly to 11 seconds, but the combined energy is still 429 (moderate). The wind is glassy – dead calm – so it’ll be absolutely perfect conditions. A very clean, lined-up morning.
From there, the surf drops off again into the second week, with only small, choppy, or onshore junk. The 18th has a tiny clean pulse, but it’s just not enough to get excited about.
So, for the whole 16-day outlook, the only two windows worth your time are the mornings of Friday the 14th and Saturday the 15th. The 15th is the absolute pick with that glassy wind and punchy 5ft swell. Crowds are often a thing here, so expect company on those days.
