Balneario Sao Jose Surf Forecast and Surf Report

Alright, let’s talk about Balneario Sao Jose. It’s a beach and pier setup, exposed to the swell, and right now the water is sitting at 69°, which is a touch warmer than usual for this time of year. That’s a nice little bonus.

The next 16 days have a bit of a slow start, but there’s some real promise later on. The first real standout is gonna be Sunday morning, August 16th. We’ve got clean, glassy conditions with a 6ft swell from the ESE. The energy’s moderate (802), and the wind is almost dead calm. It’s gonna be clean, user-friendly waves for the intermediate surfer. Crowds are often a thing here, so get out early.

Then things go pretty quiet through the middle of the week. From Monday afternoon right through to Friday morning, it’s mostly small, weak, or messy. There’s a decent window Monday morning, August 17th – still glassy, 5ft from the ESE, moderate energy (401). It’s surfable, but not a standout. Similarly, Tuesday morning, August 18th is also glassy with 4ft waves (219 energy). Not bad, but the swell is dropping.

The next real moment of glory comes Monday, August 24th, in the afternoon. That’s still over a week away, so keep that in mind, but it looks promising. A 6ft swell from the SSE with a long 14-second period is rolling in. That’s proper groundswell. The combined energy is strong at 1368. Even with a little cross-onshore wind, the quality is there. This is the kind of day where the pier might start working nicely, but that long period stuff can make a beach break a bit straight. Still, the size and power are there.

Then we get a real treat: Tuesday morning and afternoon, August 25th. Light rain, but glassy conditions both sessions. The swell holds at 5ft and 5ft from the S, with a 13-second period. Energy is still high (941 and 747). That’s clean, powerful surf. If you can get out in the rain, you’ll be rewarded. This is the best combo of size, clean wind, and quality in the whole outlook.

Thursday morning, August 27th is another glassy option with 4ft from the SSE, long period (13 seconds), and decent energy (664). Nice conditions, but not quite the standout.

Later on, Monday morning, August 31st – still two weeks away – brings a 6ft S swell with offshore wind from the N at 9 mph. That’s clean, with moderate energy (425). Could be a fun session if the forecast holds.

Overall, the real highlight is the Tuesday the 25th window. Clean glass, solid S swell, good energy. That’s the one to circle.
