Balneario Sao Jose Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s look at what’s cooking for Balneario Sao Jose.

The forecast starts off pretty average, but there’s a cracking little window coming up if you’re patient. The early week is a write-off with messy winds and small, weak swell, so don't bother paddling out just yet.

First real sign of life shows up on Wednesday morning (8th July). We’ve got a clean 3ft swell out of the SE, and the wind is dead glassy from the E. It’s not big, but with that glassy surface, the beach/pier setup will be smooth and workable. The combined swell energy is moderate (268). The water temp is sitting at 68°, which is pretty much bang on average for this time of year.

Thursday morning (9th July) is similar – another glassy morning, this time with a 2ft SE swell and a longer 11-second period, giving those waves a bit more push and shape. The combined energy is 223. Again, perfect conditions for a cruiser session.

But the standout is Saturday morning, 11th July. That’s the one to circle. The swell picks up to 4ft from the SE, with a very long 13-second period – proper groundswell energy. And it’s absolutely dead calm, glassy conditions. The combined energy jumps to 501, which is a strong, punchy signal. For a beach/pier setup, that long period means the waves will have real power and length, but they might stand up a bit quicker. It’s not too big, so it’s good for strong intermediates and above. Expect some crowds though, because this spot is often busy, especially when it’s this clean.

After that, the swell hangs around for Sunday and Monday (12th & 13th July) with clean conditions in the mornings, but nothing quite as lined up as that Saturday peak. The swell stays around 3ft to 4ft with clean light winds or offshore flow, so there are still fun waves to be had.

By the second week, from around 15th July onward, the energy drops right off. The combined swell numbers tumble into the 50s and 60s, and the swell height sits at 2ft to 2ft. The direction shifts around to the E and ESE with short periods. It’s pretty weak – not worth getting excited about unless you’re desperate for a tiny ankle-biter session. The end of the run from about 17th July to 22nd July is mostly flat to poor, with a few glassy mornings offering just a ripple.

So, to wrap it up: the best bet is Saturday morning, 11th July. Get on it early for the cleanest lines. The rest of the first week has a few decent windows, but after that, it’s going quiet for a while.

Rusty.
