The Lowdown
Alright folks, Rusty here with a look at what's on the menu for Barra da Lagoa. Gotta be straight with you, this forecast is a tough one to swallow. The next sixteen days are looking pretty bleak, and there’s a big ol’ gap of nothing-wrong on offer right from the start.
We’ve got a run of flat days with no real surfable swell for the first few days. From Thursday the 10th through to Saturday the 12th, it’s all zeros on the energy scale—nothing. Then a little spike shows up on Sunday the 13th, but honestly, it’s hardly worth getting wet for.
Let’s talk about Sunday morning. A short-period SE swell pushes in at 5ft with a period of only 8 seconds. That's a weak, crumbly wave. The combined energy is moderate at best (297). Wind is a cross-shore from the SSE at 9 mph, so it won't be clean. By the afternoon, it’s more onshore and chop. It’s small, weak, and messy. This is not the day.
The week after that is just more of the same—tiny pulses of energy, mostly under 3ft, and poor surf conditions. If you’re an absolute beginner, you might find some knee-high dribble Monday the 14th, but the wind will be onshore and the conditions choppy. It’s not looking good.
The only faint glimmer in this whole 16-day outlook is Thursday the 24th. Morning brings a clean, cross-off wind from the SSW at 6 mph. There's a small 3ft ESE swell with a short period of 6 seconds. The combined energy is weak (58), and it’s listed as "surfable waves but very ordinary conditions". If you’re desperate for a paddle and some tiny, clean waves, Thursday morning is your best bet. But don't go expecting anything special.
Honestly, this stretch feels like a write-off for any proper surfing. If kiting is your thing, with some cross-shore winds and those little bumps of swell, it might look more interesting for you than for us paddlers. For now, I’d give the board a rest and wait for the next forecast to change.
Stay patient,
Rusty
