The Lowdown
Alright, let’s call it like it is—this forecast for Barra da Lagoa is a long, flat dry spell.
From Wednesday the 19th of August all the way through to the morning of Sunday the 30th of August, there’s barely a ripple. The combined wave energy is sitting at zero for most of that time, and the few tiny bumps we see are just not worth mentioning. The water sits at 66°F, right where it should be for this time of year.
The first real chance of a wave comes on Sunday the 30th of August. That morning, we’ve got a 0.6ft swell from the SE, with a period of 8 seconds, and the energy is a weak 58. The wind is glassy—dead calm—so the surface is clean. The afternoon is a little better, with the same 0.6ft swell, period 10 seconds, and energy climbing to 96. Still tiny, but it’s surfable. The wind stays glassy. This is your only window, but it’s ordinary, small, and soft.
Monday the 31st of August brings a bit more energy—213 from the SSE—but it’s crossed with an onshore wind and quickly turns choppy and messy. The rest of the week is more of the same: small, bumpy, and not worth paddling out for.
If you’re really keen, the Sunday the 30th session is your best shot. Clean, tiny, and totally beginner-friendly, but it’s hardly a standout. The rest of the 16 days? Nada.
Rusty.
