Balneario Sao Jose Surf Forecast and Surf Report

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

First up, the water temp is sitting at 68.2°F, which is pretty much bang on average for this time of year, so no surprises there.

The week ahead is a bit of a slow grind. We’ve got a small window of opportunity on the morning of Saturday the 1st of August. The swell is a tiny 4.6ft from the east, but the period is a super short 6 seconds, so it’ll be a bit lumpy. The real kicker is the glassy, offshore wind, which will make it look a lot better than it is. It’s an intermediate wave at best, and crowds are often around, so you’ll have company. That morning is the best of a pretty average bunch.

The next few days are all about tiny, weak surf. The combined energy is low, often in the double digits, with a lot of cross-onshore wind messing things up. There’s a glassy morning on Tuesday the 4th with a bit more energy (127), but it’s still only 2.3ft. It’s surfable, but you’ll be working for it.

Now, hold on to your board, because things get real interesting on Sunday the 9th of August. The morning brings a pulse of solid 4.3ft swell from the south with a very long 15-second period. That’s a proper groundswell, folks. The combined energy jumps to a strong 748, and with a light offshore wind, the conditions are going to be clean. This is the standout session of the whole forecast. The only catch is that with a period this long, it might be a bit too straight at a beach break like this, but with the wind right, it’ll be worth a look. The afternoon gets ruined by a strong onshore wind, so get your waves in early.

The energy stays high into Monday the 10th, with a 5.2ft south swell and a 15-second period, but the wind is a cross-onshore, which will put a chop on it. It’s more of a challenging session for the experienced crew.

The second week winds down with a smaller, more manageable swell. The morning of Friday the 14th of August is a sleeper pick. We’ve got a 5.2ft SSE swell with a 12-second period, and perfectly glassy conditions with no wind. The combined energy is a solid 684, and it’ll be clean. It’s a great call for a relaxed morning session.

Overall, the first week is a bit of a write-off with small, onshore junk. The absolute standout is the morning of Sunday the 9th of August, and the glassy morning of Friday the 14th is a solid backup. The rest is just making the most of small, clean windows.
