Table - best surf conditions forecast for Barra do Sul over the next 16 days.
Alright, let’s get into it for Barra do Sul. Over the next couple of weeks, we’re looking at a stretch of small to moderate surf, but you’ll have to pick your windows carefully. The water’s sitting at 64°, which is a bit colder than usual for this time of year, so don’t forget the rubber.
The absolute standout is the morning of Saturday, July 11th. The wind is dead calm – glassy as – and there’s a clean 3ft swell from the ESE, with a 13-second period that’ll give it some real grunt. The combined energy is a moderate 335, so there’s enough power to make it fun. That’s the session to target.
Next up, the morning of Thursday, July 16th. Another glassy morning, with a clean 3ft swell from the E, period around 10 seconds. Energy is a moderate 241. It’ll be clean and rideable, a solid second choice. The morning of Sunday, July 19th, also looks okay – clean 4ft from the E with a cross-off breeze, but the period is shorter at 8 seconds, so it’ll be a bit more of a wall.
The afternoons are mostly a mess – cross-on winds and chop. From the 21st to the 24th, the surf gets really small and weak, with energy readings dropping below 100 (62-95), so don’t expect much. The mornings will still offer the odd clean window, but the juice is gone.
Focus on the 11th and the 16th. Those are your best bets.
Rusty.
