Balneario Sao Jose Surf Forecast and Surf Report

Alright, Rusty here, let's talk about what's coming up for Balneario Sao Jose.

The next couple of weeks look a bit of a mixed bag. We’ve got a few solid pulses of energy rolling through, but the winds are going to be the main character in this story for a lot of the time. There's a lot of onshore and cross-onshore breeze, which is going to be a real buzzkill, making things choppy and messy. Let’s break it down.

Right now, we’re scraping by with a small, glassy window this Wednesday morning. The swell is a tiny 2ft from the ESE with a period of 8 seconds, and the combined energy is weak (61). The wind is glassy from the NNW, so it’s clean, but it’s really just a splash-around for the longboard. The water temp is 69°, which is about 2° warmer than normal, so nothing unusual there.

The next few days are pretty grim. Thursday and Friday are mostly a write-off with poor conditions and onshore winds. The swell tries to build on Friday afternoon, hitting 5ft from the S, but it’s a short-period 7 seconds and the wind is a messy cross-onshore, making it unpleasant. The combined energy jumps to 435 (moderate), but it’s not worth paddling out for.

The weekend is a bit of a tease. Saturday morning has 5ft of S swell with a 10-second period, but the wind is onshore (SSE). The energy is moderate (375), but it’s just not clean. Sunday is similar, with smaller waves and onshore wind.

The first real standout to keep an eye on is Tuesday the 25th. The early morning is looking magic. The swell is 5ft from the S with a nice 13-second period (groundswell), and the combined energy is strong (867). The wind? Absolutely glassy calm from the ENE. This is the kind of window where Balneario Sao Jose can really shine. It’s an intermediate-level spot, so that 5ft is a fun size, but keep in mind those longer period swells can make beach breaks a bit wonky, though the glassy conditions will do wonders. It’s also a spot that’s often crowded, so expect company.

The week after that is a slow fade. There’s a decent morning on Wednesday the 26th with 3ft from the S and glassy conditions, but it’s a lot smaller. The next potential highlight isn’t until Monday the 31st of August. The morning brings a clean, glassy start with 6ft of E swell, but the period is a short 7 seconds. The energy is moderate (448), so it’s got some push, but the short period is a bit of a downer. The winds are glassy, so it’ll be clean.

Then there’s a long gap of nothing special until the following Thursday. Thursday the 3rd of September is looking like the best of the long-range. The morning has 5ft of S swell with a very long 13-second period, and the combined energy is strong (712). The wind is glassy from the SW. This is another premium window, but it’s a week and a half away, so keep your fingers crossed the forecast holds.

For the best on offer, I’d lock in Tuesday the 25th of August for the morning glass and solid groundswell. The second best is the promising Thursday morning the 3rd of September. Everything else is a bit of a gamble with the wind.
