The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, the next 16 days are a bit of a flat spell for Barra do Sul. There's nothing that really gets the heart pumping. The first recommendation doesn't pop up until Wednesday morning, July 29th, and even then it's a pretty small affair.
So, Wednesday morning, July 29th, we’ve got some tiny 2ft easterly swell rolling in. The period is a short 7 seconds, so it’s not going to have much push. The wind is glassy, which is a major positive – it’ll be clean as a whistle. The combined energy is weak (61). The water temp is about average for this time of year. It’s surfable, but very ordinary. Crowds are possible at this spot. The best bet in this whole outlook is the stand-out session on Monday morning, August 10th. The swell is still small at 3ft from the east, but the combined energy jumps to 176, which is moderate, and it’s glassy. It’s not a world-beater, but given the rest of the outlook, it’s the best you’ll get. The east swell lines up with the optimum direction for this exposed break.
There’s a long gap after that with nothing really worth paddling out for. The second week remains pretty quiet. The swell stays small, mostly under 3ft, and the wind is often cross or onshore. There’s a moment on Tuesday morning, August 11th, with a 15-second period swell from the southeast, but it’s only 1ft. That long period will make it a bit of a straight wall at the beach, so it’s not doing much for us. The very end of the forecast, on Thursday morning, August 13th, sees a 3ft southeast swell but with a 6 mph crosswind, so it’s messy.
For a few days in the middle of the second week, the swell gets a bit bigger, up to 5ft on Wednesday afternoon, August 12th, but the wind is howling at 16 mph from the south, making it a choppy, cross-shore mess. That’s more of a kite-surfing setup than a paddle session.
So, to sum it up: if you’re desperate, get out on the Monday morning of August 10th for the cleanest, most energetic little waves. Otherwise, the wait continues.
Rusty.
