The Lowdown
Alright, surfers, Rusty here. Let's break down what Balneario Sao Jose has cookin'. It's a bit of a mixed bag, with some clean windows you'll want to jump on and a few storms to dodge. The water's chillin' at 67°, which is right about average for this time of year, so no surprises there.
We're starting off pretty flat and ordinary. Wednesday the 29th has a tiny 1ft S swell, and while the morning is clean with a gentle cross-off breeze, the wave energy is weak (79). By the afternoon, it gets worse with a cross-on shore. Thursday and Friday are more of the same – small, messy, and not worth paddling out for. Honestly, it's a bit of a grim start with hardly any surf to get excited about.
But then, come Saturday morning the 1st of August, things finally turn around. The wind goes glassy and calm, and we get a clean 4ft E swell pushing in. The energy is moderate (218), and while the period is short at 7 seconds, the clean conditions should make it fun for a morning session.
Saturday the 1st of August is honestly the pick of the first week. That 4ft E swell with glassy conditions will be a real treat. The break is Balneario Sao Jose, a beach and pier setup, and it's fairly consistent here, though it can get crowded. The water's normal temp, the vibe should be good. The swell is from the east, and the optimum is from the SE, so it's not a perfect match, but the clean wind more than makes up for it.
After that, things go quiet again through Sunday, Monday, and Tuesday morning. We get small pulses, but nothing worth rushing out for.
Now, Thursday the 6th of August looks promising. We've got a 5ft E swell, which is getting a bit meaty, but the wind is a solid offshore from the N at 9 mph, keeping it clean. The energy is strong (440), and while it's not a groundswell, it's a decent push. This one is worth marking on your calendar.
The real standout, the one you've been waiting for, is Thursday the 13th of August. The sky's partly cloudy, the wind is glassy from the SSE, and we've got a clean 4ft S swell rolling in. The period is a sweet 12 seconds, so it's proper groundswell with real shape. The energy is very strong (556), so expect some solid lined-up sets. This is the best surf on offer in the whole 16-day stretch. Point breaks and reefs will love this, but at a beach break, it might line up a bit straight, so look for the banks. The wind will be offshore and glassy, so it's going to be clean as a whistle.
After that, the swell drops off and conditions turn average again with onshore winds kicking in.
So to sum it up: the first few days are a write-off. Saturday the 1st of August is your first good chance for a clean session. The one true standout, the one to plan around, is Thursday the 13th of August. Don't sleep on it.
Rusty.
