The Lowdown
Hey folks, Rusty here. Let’s talk about what’s on the cards for Balneario Sao Jose. This spot is a beach and pier setup, exposed to any swell coming in.
Right now, the first week is a write-off. From Thursday the 30th of July right through until Sunday the 9th of August, it’s a brutal stretch of tiny, wind-affected slop. The combined energy is pathetic – we’re talking values between 40 and 261 – and the winds are either onshore or cross-onshore, keeping things choppy and blown out. You’re looking at a solid week and a half of poor to ordinary conditions. There's just no reason to paddle out until things change.
Now, let’s talk about the real standout. You have to circle Tuesday the 11th of August. Tuesday afternoon looks firing. The swell is solid, hitting about 5ft, out of the SSE with a very long period of 16 seconds – that’s proper groundswell energy. The combined energy jumps way up to 971 (strong energy), and the wind goes glassy with a slight air moving. This is going to produce clean, powerful lines with those long gaps between sets. For a beach-and-pier setup, that long period can make things break a bit straight, but with that energy and zero wind, it’s a paddler’s paradise if you can sit in the right spot. This is the best on offer.
The next morning, Wednesday the 12th, is also a solid runner-up. Wednesday morning stays glassy and calm, with a 4ft SSE swell (period 13 seconds) and combined energy at 532 (moderate-strong). It’ll be a touch smaller than the day before but still clean and very surfable.
Water temp is sitting at 68°, which is about 0.7° above the long-term average for this time of year – so normal warmth, nothing out of the ordinary.
So, in short: don’t waste your time for the first 10 days. Wait for that Tuesday the 11th afternoon and Wednesday morning window. That’s where the magic lives.
Stay wet, Rusty.
