The Lowdown

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

Honestly, it’s a pretty quiet start. For the first few days, there’s hardly any juice in the water. Tuesday the 28th has clean, glassy conditions with a tiny 1ft south swell, but the energy is really weak at just 95. It’s surfable, but you’ll be working hard for small, ordinary waves. The water temp is sitting at 66°, which is pretty much normal for this time of year, nothing unusual.

We’ve got a long stretch of small, average surf through the rest of the week and into the weekend. Wednesday the 29th morning has a bit of a cleaner look with a cross-off breeze, but the swell is still only 1ft. A few spots on Thursday and Friday mornings offer a glassy surface, but the wave size stays stubbornly small, around 2ft to 2ft, and the energy is often in the weak range (63 to 154). It’s not terrible, but it’s not turning heads.

Saturday the 1st of August has a morning of dead calm, glassy conditions with the swell bumping up to 4ft, but the period is a short 7 seconds, so it’s going to be a bit mushy and disorganised. The energy is moderate (199). Worth a paddle if you’re desperate, but it’s not the standout.

The real standout window opens up on Tuesday the 4th of August. The morning sees a clean, glassy surface with a solid 2ft south groundswell. The period is a nice long 12 seconds, and the energy bumps up to a moderate 229. This is the best-looking session in the first week. The offshore wind direction is N-NW, so it’s clean. The break is an exposed beach/pier, so with that longer period, it might be a wee bit straight, but with the glass, it’s worth a look. Crowds are listed as "often" here, so expect company.

After that, the surf stays small and ordinary through to the 8th of August. There’s a promising morning on the 8th with a glassy 3ft east swell (9s period) and a score of 2, but it’s still not a barnburner.

Now, the second week gets interesting. On the 10th of August, Monday morning, we’ve got glassy conditions again with a 3ft south swell, a long 12-second period, and strong energy at 255. That’s a solid call. By the 12th of August, Wednesday afternoon, things really ramp up. The swell jumps to 6ft from the south, still with a 9-second period, but the energy is very strong at 553. The wind goes glassy, and the forecast calls for "very good surf conditions." That’s the pick of the whole outlook. Keep in mind, 6ft is getting into the intermediate-to-expert zone, especially if it’s a bit punchy, so beginners should be cautious.

The 9th of August also sees a big pulse of energy (523) with a 4ft south swell and a very long 14-second period, but the wind is onshore, making it a messy prospect. That longer period at a beach break might make it a bit too straight.

All in all, your best bet is the morning of Tuesday the 4th for a clean, glassy session, and then keep an eye on the 10th and especially the 12th of August for the biggest, cleanest swell of the period.

Stay wet,
Rusty.
