Balneario Sao Jose Surf Forecast and Surf Report

Alright, Rusty here. Let's take a look at what Balneario Sao Jose has cooking for us over the next couple of weeks.

Right off the bat, there’s a bit of a lull to start. The first real action we see is on Thursday morning, the 27th of August. It’s not a bad morning, with a solid 6ft swell from the SSE and a very long 14 second period, packing a whole lot of energy. The water is a touch warmer than normal at 70°, which is nice. The wind is glassy out of the NE, so it’ll be clean. But that’s a big, long-period groundswell hitting an exposed beach setup, meaning it’ll be powerful, a bit heavy, and definitely one for experienced surfers only. Not a beginner spot that day.

Thursday afternoon takes a turn. The swell drops to 5ft and the wind swings to a cross-onshore, making things choppy and marginal. We skip Friday and Saturday as they offer small, short-period windswell and ordinary conditions. The wind stays clean early Friday morning with 5ft from the east, but it’s only 7 seconds of period, so it’ll be a bit weak and crumbly.

Then we hit a dry spell. From Sunday, the 30th of August, right through to Tuesday, the 1st of September, the surf is poor. Tiny waves, weak energy, and onshore winds. Not worth your time. Wednesday the 2nd of September sees a spike again – a 7ft SSE swell with a 12 second period and a huge punch of energy. This is big for the area. But it comes with a strong onshore wind, making it a messy, blown-out affair. Friday morning the 4th and Saturday the 5th offer little more than knee-high leftovers.

Now, here’s where we get the standout. The 10th of September, Thursday morning, looks bloody good. A clean 6ft swell from the SSE, with a short 7 second period, but glassy winds from the ENE. The energy is solid. That combo will give you fun, punchy waves without the crazy power of a groundswell. Then later that same Thursday afternoon, we get a second treat – a 3ft, 12-second S swell that is absolutely glassy. It’s small, but that long period will wrap in nicely.

Following that, Friday the 11th of September morning and afternoon are both top-notch. You’ve got a 4ft S groundswell with a 12-second period, clean offshore breezes in the morning, and flat-out glass in the afternoon with a big energy reading. For such a small-looking wave height, that’s some serious push. That Friday is the moment to clear the calendar.

Remember, this is a beach and pier setup, so those long-period swells will be a bit shifty, but when the wind is right, it can be a blast. Overall, the pick of the litter is that 6ft SSE on the morning of the 10th, and the long-period S swell on the afternoon of the 11th. Get on it.
