The Lowdown
G’day, Rusty here. Let’s have a look at what’s on offer at Balneario Sao Jose over the next couple of weeks.
We’ve got a bit of a slow start, but there’s some fun stuff building. The water’s sitting at 66°F right now, which is pretty much bang on average for this time of year – nothing to write home about, but you won’t need a thick steamer.
The first real standout is Saturday morning, the 1st of August. That’s the pick of the early run. We’re expecting clean, glassy conditions with a 4ft swell out of the ESE, period around 7 seconds. The wave energy is moderate (207), and with the wind off the land, it’ll be tidy. It’s a beach/pier setup, so it’s not gonna be a world-class point break, but for a Saturday sesh, this is where you wanna be. Keep in mind, crowds can be common here, so get in early.
Then we hit a bit of a lull through the first week of August. A few mornings are glassy, but the swell drops right off – 2ft to 3ft – and the wind switches around. Nothing worth paddling out for, honestly. The 4th of August (Tuesday morning) is glassy but tiny (2ft, 103 energy), so you’d be chasing ankle-biters.
The next real standout lands on Thursday morning, the 6th of August. The swell bumps up to 4ft from the south, period 9 seconds, and the energy is solid at 324. It’s going to be glassy – dead calm – so the surface will be like a mirror. That’s a good morning for a longer board, and the waves will have a bit more push. Not a monster, but quality.
But the best of the whole run? That’s Friday morning, the 7th of August. Swell jumps to 4ft out of the SSE, with a period of 12 seconds – that’s proper groundswell. The energy is pumping at 472. It’s glassy, zero wind, and the break should be handling it well. Just a heads-up: with that long period (12 seconds) and a beach/pier setup, it can sometimes close out a bit, but the clean conditions will make up for it. This is the one to circle on the calendar.
After that, Saturday the 8th still has some clean leftover energy (3ft, 11-second period, 204 energy) with a cross-off breeze, so it’ll be fun but not as epic.
The second week gets messy. From Sunday the 9th onward, we’ve got rain and onshore winds. The swell actually gets bigger – 5ft to 5ft on the 12th of August – but it’s cross-onshore and choppy. The energy is huge (over 1000), but the quality is poor. That’s more of a kite session than a paddle session, to be honest. Nothing for the surfer there.
So, to sum it up: Saturday morning the 1st of August is a clean little winner, but the absolute standout is Friday morning the 7th of August. Get out there for that one.
Rusty.
