The Lowdown
Alright, Rusty here. Let's get real about Balneario Sao Jose (Brazil). The outlook is pretty flat for the next couple of weeks. The swell energy is weak, mostly under 200, and the wind is a pain in the neck most days. There's no real standout swell, just a few clean windows if you're desperate for a paddle.
We start on Monday, July 27th with a tiny 3ft SE swell, period a short 8 seconds. The water temp is 68°F, which is about average for this time of year. The morning is glassy, which is nice, but the swell is so weak and short it's barely gonna wrap. The combined energy is only 147, so it's really weak. Monday afternoon turns cross-on and the quality goes to crap.
Tuesday the 28th is a similar story – a glassy morning with a 3ft ESE swell, but it's still weak. The afternoon sees a 2ft S swell with a slightly better 11-second period, still glassy, but it's tiny. The energy bumps to 166, but it's nothing to get excited about.
Wednesday the 29th and Thursday the 30th are small and weak, with S swells around 1ft to 2ft. The mornings are clean or glassy, but the energy is pathetic, dropping to 78 and 76. It's really just a waist-high dribble, if that.
Friday the 31st and Saturday the 1st of August are a washout. Cross-on winds and poor conditions. Saturday morning actually has a small bump to 4ft from the ESE, but the period is a shocking 6 seconds. That's pure wind chop, not worth your time. The energy is 150, but it's messy.
Now, Sunday the 2nd of August morning is the best of a bad bunch. Glassy conditions, light offshores, and a 3ft ESE swell with a 7-second period. It's still short-period, but the energy is 126, and the glass is gonna make it look more rideable than it is. The afternoon goes cross-on again, so that window is tight.
Monday the 3rd of August has a glassy morning with a 3ft ESE swell, and the afternoon goes glassy too with a 3ft E swell. The energy is 98 and 138, so it's still weak. If you're a beginner, these are your best bet, but there's no power.
The rest of the week into the second week (4th to 11th of August) is a long, drawn-out stretch of tiny surf, mostly under 3ft, with periods anywhere from 6 to 12 seconds. The wind is a mess – cross-on, onshore, or cross-shore chop. The only glimmer is the morning of Sunday the 9th of August, where it's glassy with a 2ft S swell, 11-second period, and energy of 153. It's clean, but it's small. The 8th of August morning has a 3ft S swell with a 12-second period and energy jumping to 308, which is moderate, but it's cross-shore wind, so it's gonna be a bit lumpy.
Honestly, there's no standout session here. The 4ft on Saturday the 1st with glassy wind is the only real contender, but the 6-second period kills it. If you're a beginner, those glassy mornings with tiny 2ft to 3ft swells are safe fun. The water temp stays around 68°F the whole time, so a wetsuit is a good idea. It's a long, flat spell, but it won't stay poor forever. Keep your eyes peeled.
Rusty.
