The Lowdown

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

First off, don’t get too excited just yet. The start of the week is a bit of a slow burner. The water temp is sitting at 66°, which is pretty much average for this time of year – nothing to write home about, but you won’t need a full steamer.

Monday afternoon is a write-off. We’ve got a 6ft S swell, but it’s coming in with a cross-onshore wind and the energy is a moderate 527. It’s choppy and messy. Not worth paddling out for.

Tuesday morning, 14th July, is where it starts to look a little more interesting. The swell drops to 5ft from the SSE, and the wind goes glassy. That’s a major positive. The energy is still moderate at 408. It’s not pumping, but it’ll be clean. Wednesday morning, the 15th, is another good shout. The swell holds at 5ft from the SE, wind is light cross-off, and the energy bumps up to 536. Expect clean, lined-up waves. That’s your best bet for the early part of the week.

Thursday morning, the 16th, is glassy again with a 5ft ESE swell, but it’s a bit weaker at 459 energy. Still, a fun little session if you’re keen. After that, the swells drop off into the weekend. Friday and Saturday the 17th and 18th see waves around 3ft to 3ft. The wind is light, so it’ll be clean, but it’s small. The energy drops to 293 and then 212. Not a standout, but if you’ve got a log, you’ll have fun.

There’s a bit of a lull from Sunday the 19th through to Tuesday the 21st. The waves are tiny, around 2ft to 3ft, with energy dropping as low as 72. It’s pretty flat. A few days of nothing much.

Now, look ahead to Thursday the 23rd of July. That’s a real standout. We’ve got a 4ft S swell, but it’s a long-period groundswell at 12 seconds. The energy is a solid 540. And the wind? Glassy. Completely glassy. That’s going to be clean, lined-up, and the sets will have some punch. If you can get on it, that morning session is the pick of the whole forecast.

Friday the 24th morning is also good – 4ft S swell, 12-second period, light offshore wind, energy at 451. Clean again. The following Sunday the 26th morning has a bigger 6ft ESE swell, but the period is shorter at 8 seconds. The energy is 507, and the wind is cross-off, so it’ll be clean but a bit more walled up. Still worth a look.

The 23rd is the one to circle. That glassy, long-period S swell is going to be the best of the run.

This is Rusty, signing off.
