The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this outlook for Barra do Sul is a bit of a mixed bag. The next couple of days are quiet, but there’s a good window of surfable waves from Wednesday morning, August 26th, through to the start of September. The water’s running at 67°F, which feels pretty normal for this time of year – no dramatic shift from the long-term average.
The first real standout is Wednesday morning, August 26th. You’ve got a 3ft groundswell rolling in from the southeast, with a long, juicy period of 16 seconds. The combined wave energy is solid, sitting at 468 (moderate energy), and with that 3 mph westerly wind going offshore, the surface will be clean and inviting. For a beginner-friendly spot like this, the size is perfect. That southeast direction is spot on for what this break likes to see.
Then, we’ve got a run of solid mornings. Thursday morning, August 27th, offers 3ft from the southeast, period 14 seconds, with glassy conditions under a light northwesterly breeze – wave energy at 341 (moderate). Friday morning, August 28th, sees a shift to a 4ft easterly swell, though the period drops to 8 seconds, so it’s more of a wind swell. Still, with glassy conditions and a northwesterly wind, it’s well worth a paddle. Saturday morning, August 29th, is similar: 4ft from the east, period 8 seconds, glassy with a northwesterly – wave energy at 244 (moderate). The pattern holds into Sunday morning, August 30th, with 3ft from the east, period 9 seconds, a south wind at 3 mph making it glassy, but energy drops to 166 – still surfable, just a bit weaker.
Into the second week, Monday morning, August 31st, has 4ft from the east, 9-second period, with a light southwesterly wind giving you glassy conditions and moderate energy at 198. Tuesday, September 1st, is another cracker: 3ft from the east-northeast, period 9 seconds, with a 3 mph west-northwesterly wind making it glassy (energy 254). The afternoon even offers 3ft from the east-northeast with a 9 mph offshore wind from the west-southwest – clean and punchy, energy at 214.
After that, the quality tails off. Wednesday morning, September 2nd, has 4ft from the southeast, 10-second period, with a light cross-offshore wind from the west-southwest, energy at 294 – still clean, but the surf gets more average into Thursday and Friday. By Sunday, September 6th, the swell drops right away, with just 1ft and weak energy (49). The rest of the forecast is a long, flat stretch with poor conditions and onshore winds, nothing worth chasing until maybe Wednesday, September 9th, but that’s marginal at best (3ft, east, 7-second period, 203 energy, but cross-onshore and rainy).
Best bets? Lock in Wednesday morning, August 26th, for the clean, long-period groundswell. The Saturday morning, August 29th, is also a strong call – consistent size, clean, and beginner-friendly. If you’re free, go get wet.
Rusty.
