The Lowdown
Alright, let’s talk surf for Balneario Sao Jose. It’s a beach/pier break open to the south swell, and it’s a slow start.
The water is 68°, right where it should be for the season.
The first real chance is Sunday morning, July 26th. We’ve got a flat calm morning with a 0.7m south swell, 13-second period, but the energy is weak (315). It’s clean, but barely breaking. Monday and Tuesday offer tiny, short-period dribble that’s not worth paddling out for.
From Wednesday the 29th through the 3rd of August, it’s a real dead zone. The swell dries up, and most days are dominated by poor, cross-onshore winds. It’s a proper waiting period.
Things fire up on the 4th of August. Tuesday morning shows a clean 0.9m south-southeast swell, 11-second period, with a combined energy of 218. The wind is light cross-offshore, making for a clean, fun session. It’s the first real sign of life.
The big winner is the 5th of August. Wednesday morning delivers a 1.4m east-southeast swell with a 9-second period and a combined energy of 353. The wind is cross-offshore, keeping it clean. This is the biggest and most powerful swell of the entire outlook. Wednesday afternoon gets even better with glassy conditions and a 1.3m swell. The 7th of August also has a killer morning with a 1.3m south swell, glassy wind, and a massive combined energy of 557, but it gets blown out in the afternoon, so get out early.
After that, it settles back into smaller, ordinary waves for the 8th and 9th, with the 9th afternoon offering a bumpy, but rideable, 1.2m swell.
The real standout is the 5th of August for the biggest, cleanest swell of the run. The 4th and 7th of August mornings are also solid picks. You’ll have to wait for it, but it’s worth it.
