Balneario Sao Jose Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for Balneario Sao Jose over the next couple of weeks.

Right off the bat, it’s a bit of a slow start. The first few days are pretty ordinary, with only small, short-period swell and tricky winds. The water temp is sitting around 20°, which is pretty much normal for this time of year, so no need to dig out the extra thick wetsuit just yet.

Friday the 24th is a write-off, with a messy 4ft S swell and cross-shore winds. Not worth paddling out for. Saturday morning the 25th shows a glimmer of hope – the wind goes glassy, and the swell is a clean 4ft from the SSE, with a period of 9 seconds. The combined energy is moderate (284), and it’s the first real chance for a decent session. The wind is off, the waves are tidy, but it’s a beach break, so it might get a little sectiony. Sunday morning the 26th offers a similar story: glassy conditions with a 2ft S swell, but the period jumps to 13 seconds, which is a long groundswell. That longer period might make it break a bit too straight for a beach break, but at least the energy is still moderate (320). The crowd situation is “often” here, so expect some company.

Then we hit a dry spell. From Monday the 27th right through to Friday the 31st, it’s a frustrating run of tiny swell, poor wind, and very ordinary conditions. The energy drops right off, with values like 138 and 85, and swell heights barely scraping 1ft to 2ft. It’s a real lull, and honestly, there’s nothing worth chasing.

Now, hold onto your board, because Saturday the 1st of August brings a pulse. The swell jumps to 5ft from the E, but the period is a short 6 seconds, and the wind is cross-shore. The energy is moderate (430), but it’s not clean. Sunday the 2nd is still struggling with onshore winds.

The real standout, the one you’ve been waiting for, is Thursday the 6th of August. The morning is glassy, with a solid 7ft swell from the ESE, a period of 10 seconds, and a combined energy of 832 – that’s strong wave energy. This is a proper groundswell, and with the wind off, it’s going to be clean and powerful. This is expert territory, as it’s over 8ft for the bigger sets. Friday the 7th is also a cracker, with glassy conditions again, a 6ft ESE swell, and energy at 598. It’s still a big, solid groundswell, so respect the power.

Saturday the 8th of August sees the swell drop back to 4ft, but it’s still glassy in the morning, making for a fun, clean session to wind down the forecast period.

So, to sum it up: the first week is a bit of a grind, with only a couple of glassy windows on the 25th and 26th. The real pay-off is the second week, especially Thursday the 6th and Friday the 7th of August. Those are the days to clear your schedule. The swell is big, the direction is good, and the wind is perfect. Just be aware that the crowd factor is “often” here, so get there early.

Rusty.
