The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s cookin’ at Balneario Sao Jose for the next couple of weeks.
First off, we’re starting with a whole lot of nothin’. The first few days are just tiny, weak waves and funky wind. There’s a big gap of flatness before we get to any real action. You’re gonna have to be patient.
The absolute best bet is Saturday morning, August 1st. It’s gonna be glassy, dead calm, and we’ve got a pulse of east swell pushing in. Wave height is around 5ft, but the period is short at 7 seconds, so it’ll be a bit choppy and fast. The energy is strong (444), and with zero wind, it’s the cleanest morning we’ll see. The water temp is 67°, which is dead average for this time of year. This one’s for the intermediate crew, not the beginners.
Another decent window, though a bit further out, is Friday afternoon, August 7th. The wind goes glassy again, and we get a new ESE swell. The height is only 3ft, but the energy is solid (318) and the period hits 8 seconds. It’s a clean, fun afternoon session if you can wait for it.
In between, the Sunday and Monday morning sessions (August 2nd and 3rd) offer tiny, glassy waves, but they’re really just for the longboard or a paddle. Not worth a special trip.
Later on, Tuesday afternoon, August 11th, we see another pulse. The swell is 5ft from the SSE, with a cross-offshore wind from the west. It’s a cleaner look, but the energy is moderate (239). The short period (7 seconds) will keep it a bit messy, but it’s a solid option for a weekday surf.
The wind is the real wildcard. We get some good, clean windows, but a lot of the time the onshore or cross-onshore wind will chop things up. The beach/pier setup doesn’t love the short-period swell, so when the wind’s on it, it’s a kite-surfing day, not a paddling one.
Bottom line: Saturday, August 1st is the one to chase. The rest is a waiting game for a few fleeting moments of glass.
Rusty.
