The Lowdown
Alright, let’s get into it. Look, I’ll be straight with you—this stretch is a real grind. We’re looking at Barra do Sul, and for the first week and a half, it’s pretty much a flat spell. The wind is mostly light and offshore or glassy in the mornings, which is a tease, but the swell is tiny and weak. The combined energy is barely registering (39 to 100) for days on end, so you’re not missing much. Saturday morning the 1st of August, the water’s sitting at 66°F, which is about average for this time of year, so nothing weird there.
The first real glimmer of hope comes on Tuesday the 11th of August. Tuesday morning, we’ve got glassy conditions, a light 3ft swell out of the SE with a long period of 14 seconds, and the energy jumps to 354 (moderate). That’s groundswell with some punch, though that long period might make it a bit bowling at the beach. Still, clean and glassy, it’s the best of a quiet run.
Then, hold onto your board—Sunday the 16th of August, morning session. This is the standout. Clean, offshore cross-off wind from the WSW, and a solid 6ft swell from the SSE with a 12-second period. The energy is a massive 1345 (strong to very strong). That’s a proper swell, but at 6ft, it’s getting into expert territory if you’re not confident. The break is exposed and the swell direction is close to the optimum E, so it should line up well. Afternoon drops off to 2ft, so the morning is the window.
The rest of the 16 days? Mostly weak, poor surf conditions. A few mornings with clean, surfable but very ordinary waves (2ft to 3ft), but nothing to write home about. The gap between the 1st and the 11th is a long, dry stretch. This area is fairly consistent usually, but this run is a definite lull. If you’re a kiter, those afternoons with cross-on wind and 4ft+ might be more interesting.
