Balneario Sao Jose Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s headed our way down at Balneario Sao Jose. This is a beach and pier setup, exposed to the swell, and it’s about as consistent as they come around here, so there’s always a chance.

The water temp is sitting at 68°, which is pretty much normal for this time of year, so don’t expect any surprises on that front.

The next few days are a bit of a mixed bag. We’ve got some small, short-period windswell rolling in, but the winds are mostly light and variable, with a few glassy windows. Saturday morning starts off with a tiny 4ft swell from the east at 6 seconds, and it’s glassy. The wave energy is weak (294), so you’re looking at small, weak waves, but it’s clean. Sunday morning is a bit better with a 3ft east swell, still glassy, and light offshore wind from the north. The energy is moderate (117), but the waves are very ordinary. The better bet is Saturday afternoon, with a 2ft, 11-second south swell, though the cross-onshore wind messes it up. Monday and Tuesday are small and glassy, but the swell is tiny—2ft and 1ft—so you’re really just getting a paddle.

Then things start to wake up. Friday the 7th is the first real standout. Friday afternoon pulls in a 4ft south swell, 8-second period, with glassy conditions. The combined energy is moderate (208), and the waves are clean. It’s a solid window for a quick session after work.

Saturday the 8th is a gem. We’ve got a 4ft south swell, 9-second period, and a clean offshore wind from the NNW at 9 mph. The energy is solid (221), and the conditions are clean. This is your best bet for the first week—nothing too big, but well-shaped and fun.

Now, the second week brings some serious power. On Monday the 10th, the afternoon sees a 6ft south swell, 9-second period, with glassy conditions and a big jump in energy (540). That’s a solid step up in size, and the surf is looking very good.

But the real beast comes in on Tuesday the 11th. The morning has a 8ft south-southeast swell with a very long 17-second period, and the energy is pumping at 4971. That’s a massive groundswell. The wind is a bit cross-onshore, but the afternoon cleans up with a 7ft swell from the same direction, 16-second period, and a cross-off breeze. The energy is still huge (2365). These waves are powerful, long-period, and definitely for experienced surfers only. The swell direction is right on the money, coming from the optimum southeast. This is the standout of the whole forecast, but the long period means it’ll be best on the pier or a reef setup—beach breaks might get a bit straight and hard to handle.

After that, the swell drops off but stays punchy. Wednesday the 12th is messy with strong cross-shore winds, but the energy is still there. Thursday the 13th through Saturday the 15th sees smaller, cleaner windows, with a 3ft to 3ft south swell and glassy conditions on Saturday morning.

Overall, the first week is small and clean, the second week fires up with a big swell event. The absolute best on offer is Tuesday the 11th for the powerful, long-period groundswell, but you’ll want to be an experienced surfer. The next best is Saturday the 8th for clean, fun waves without the drama.

Rusty.
