The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s on the cards for Balneario Sao Jose over the next couple of weeks. We’ve got a bit of a slow burner here, with some promising windows if you’re patient.
The water is sitting at 67°, which is pretty much normal for this time of year, so nothing unusual to worry about there.
We start off on Monday the 20th of July, but honestly, it’s not much to write home about. The swell is small, around 3ft from the ESE, with a short period of 8 seconds and weak energy (119). The wind is a light cross-off, so the surf is clean, but it’s just ordinary. There’s a bit of a lull in the quality, with nothing really kicking off through Tuesday and Wednesday.
Thursday the 24th of July is where things start to perk up a little. Friday morning we get a glassy 3ft from the south, with 9 seconds of period and combined energy climbing to 177. It’s still not huge, but it’s clean. Saturday the 25th continues that trend – glassy conditions again, with 4ft from the SSE in the morning. It’s the best run of the first week, but it’s still just ordinary surf.
Then Sunday the 26th gets messy. The wind swings around to the SSW at 12 mph, blowing cross-onshore. The swell jumps to 4ft from the SE, but the energy gets up to 324, and the period is 9 seconds – it’s just not clean. The afternoon sees a long period 13 second groundswell from the south at 3ft, with energy hitting 415, but the onshore wind ruins it. It’s a pass for paddle surfing.
Now, if you can hold out, Monday the 27th of July is a standout. The morning is glassy, with a 3ft south-east swell at 9 seconds and energy of 201. It’s clean, it’s lined up, and it’s a proper session for the patient surfer. Tuesday the 28th is also a beauty – absolutely calm, glassy conditions, with a 3ft south-east groundswell, period of 10 seconds, and energy of 233. That’s a solid, clean, fun day.
The first week of August? It’s a mixed bag. Saturday the 1st of August has a morning standout potential. It’s dead calm, glassy, with a punchy 4ft from the east. The period is short at 6 seconds, but the energy is 283. It’s a bit of a close-out risk at a beach break with that short period, but the conditions will be perfect. After that, it’s a bit of a drop-off again, with onshore winds and choppy conditions through Sunday and Monday.
The last few days, the 4th and 5th of August, are back to ordinary, clean but small east-south-east swell. All in all, your best bets are the glassy mornings on the 27th and 28th of July, and maybe the morning of the 1st of August. Keep your eyes on those.
Rusty out.
