The Lowdown

Alright, Rusty here. Let’s break it down for Balneario Sao Jose.

Honest truth – for a good while, we’ve got a real slow patch. The first week-plus is mostly small, with a lot of just “ordinary” surf. The water’s sitting at about 68°F, which is normal for the season.

We start properly on Sunday the 26th with a tiny 3ft S swell, period just over 13 seconds, so there’s some groundswell there, but it’s cross-onshore and messy. Energy is just moderate at 326. Not much to get excited about.

Monday morning the 27th is glassy, which is nice, but it’s even smaller at 2ft from the SE with a short 8-second period. That’s weak (149 energy). The afternoon goes cross-onshore and is a washout.

Through the rest of the week we get a few glassy windows – like Tuesday the 28th afternoon with a 2ft S swell and a long 12-second period (184 energy), and Thursday the 30th afternoon with another glassy patch on a 2ft S swell (86 energy). Clean, but tiny. You’d be on a log.

There’s a bit of a spark on Friday the 31st morning – the best of the early run, glassy, a 3ft SSE swell with a 10-second period and the energy climbs to a solid 206 (moderate). Worth a look, but not a standout. The afternoon turns onshore again.

Saturday the 1st of August is glassy both sessions with S swell around 2ft to 2ft, nice to look at, that’s it.

Now here’s the real deal. The standout is Tuesday the 4th of August morning. The combo energy hits 333 (strong), with a 3ft SSE swell and a long 12-second period. Glassy conditions. That’s the best wave of the whole outlook – clean, good shape, decent push. Thursday the 6th of August morning is another good one: glassy, 3ft SE swell, 10-second period, and energy at 300 (strong). Those two morning sessions are where it’s at.

After that, it’s back to small, short-period, onshore junk from the 7th onward.

So, bottom line: first 9 days are for the patient or the longboarder, with the 31st July morning being the best in that period. The real winner is Tuesday 4th August morning – that’s the session to circle. Thursday 6th August morning is also a solid second pick. The rest? Not worth the drive.

Rusty.
