Balneario Sao Jose Surf Forecast and Surf Report

Alright, let’s get into it.

First up, it’s a bit of a slow start for the next few days. We’ve got some tiny waves and ordinary conditions, but nothing that’s gonna get the heart racing. There’s a real gap here to start the run. For the first few days, you’re looking at ankle-biters and poor surf. It’s not a total blank, but it’s close to it. Don’t get too twitchy, though. This kind of quiet spell doesn’t usually last long around here.

Now, looking at the first real pulse of energy. We finally see a proper groundswell start to fill in on the 9th. Early morning that Sunday is the call. The swell direction is from the south at 4ft, with a long 17-second period. That’s a proper groundswell, the kind that has some serious push behind it. The energy reading jumps to 698, which is solidly in the moderate zone, and it’s glassy with a light offshore wind. That’s a clean setup. At this size, it’s friendly for intermediates, but that long period might make it a bit roly-poly.

The standout here is going to be at Balneario Sao Jose. This exposed beach/pier setup is right in the firing line for a south swell. That early morning window on the 9th is your best bet. The swell direction and the period are the key; it’s got that long-period energy that just makes the waves feel so much better. The tide might be a little questionable later, but the morning looks clean.

After that, things get a bit messy for a few days. We’ve got a run of onshore winds and rain starting on the 11th and lasting through the 13th, with surf size bumping up but quality dropping off a cliff. It’s gonna be choppy and blown out. I’d sit that stretch out.

Then, we have another proper highlight shaping up. The 15th looks good again. We’ve got a clean morning with south swell at 5ft and an 11-second period. It’s glassy with light winds. The combined energy is strong at 644. This is a bigger, more powerful day. At 5ft, it’s starting to get a bit more serious. It’s pushing past that beginner-friendly zone, but for the intermediate crowd, this could be the best of the bunch.

Looking further out, there’s a pulse of energy on the 16th with a very long period swell (15 seconds) and a big jump in the energy reading to 1223. That’s strong to very strong wave energy. But the catch is it’s onshore and rainy, so the quality is going to be compromised. There’s a lot of power there, but the wind is going to mess it up.

So, for the pick of the litter: the early morning of the 9th for the first clean, long-period groundswell, and the morning of the 15th for a bigger, more powerful, and still clean day at Balneario Sao Jose. That 15th is the one I’d be circling on the calendar. It’s got size, period, and clean conditions. The longer-range stuff is promising but less of a sure thing.

Anyway, the water temp is sitting at 68°, which is a touch above average for this time of year. It’s not a big deal, but it’s a little friendlier than usual.

Rusty out.
