Balneario Sao Jose Surf Forecast and Surf Report

Alright, it’s Rusty here. Let’s talk about the next 16 days at Balneario Sao Jose. The overall vibe is pretty quiet. There’s a bit of a gap before anything really worth getting in the water for, so hang tight.

Right now, the surf is flat and nasty. A few small, weak pulses from the south (2 ft) with a cross-onshore wind and poor conditions. The energy is low (66). The water temp is 68°, which is pretty normal for this time of year. Don’t bother paddling out yet.

The first real window opens up on the morning of Saturday, August 1st. That’s when we get a little pulse of east swell, 5 ft, short period of 7 seconds. The wind is glassy offshore (NNE breeze at 3 mph), so it’ll be clean. The energy is moderate (434). This is a beginner-friendly size, but the short period means it’ll be a bit soft and ripply. Still, the best on offer in this first week. Crowds are often a thing here, so expect some company.

Sunday morning, August 2nd, is also surfable but smaller. East swell drops to 3 ft, still short period, but the wind is cross-offshore and clean. It’s a “clean” wave, nothing special, but okay for a longboard session.

After that, things get ordinary again. A few days of tiny, messy waves and poor conditions. The energy is weak to moderate (51-258). There’s a glassy morning on August 7th with a 2 ft south swell, but it’s too small to get excited about.

Then, on Saturday, August 8th, we get a bit of a bump. The swell picks up to 5 ft from the SSE (9 seconds), with a cross-offshore wind in the morning, and glassy conditions by the afternoon. The energy is solid (303-297). This is another standout for the period, especially for intermediates. The swell direction is a good match for the beach-pier setup, but the period is still short, so don’t expect hollow waves.

The second week gets a bit more interesting energy-wise but the wind is worse. On Monday, August 10th, the swell jumps to 5 ft from the SSE, but with a very long period of 15 seconds – that’s a proper groundswell. The energy is strong (1034). Problem is, it’s onshore, with light rain and a SE wind. That combo will chop it up, and at 5 ft, it’s pushing past beginner territory. The long period tends to make beach breaks close out, so it might be more interesting for the reef or river mouths if there were any around here. That afternoon is rated marginal, but the wind is against it.

Later in the week, the swell drops off again. The mornings of August 13th and 14th have tiny, glassy waves (3 ft to 2 ft) from the east, but the energy is weak (118-58). A complete non-starter for anything serious.

Honestly, the best bets are the glassy morning of August 1st and the clean windows on August 8th. Everything else is either too small, too windy, or just ordinary. It’s not a total blank, but you’ll be picking your moments.

Rusty.
