Balneario Sao Jose Surf Forecast and Surf Report

Righto, surf’s up… or it will be. Let’s be straight with you – the next few days are a bit of a write-off. We’ve got a poor run of conditions with onshore winds and lumpy, sloppy surf. But don’t go hanging up the wettie just yet. There’s a real window of opportunity coming in the middle of next week that looks like the pick of the bunch. It’s a waiting game, but it should be worth it.

The first proper call is Monday morning, September 14th down at Balneario Sao Jose. The ocean finally turns it on. We’ve got a clean 8ft of SE swell pushing through, with a period of 8 seconds. The wind is dead glassy, and the water is a touch warmer than normal for this time of year at 70°. The wave energy is moderate, sitting at 682. This is the standout – clean, decent size, and your best chance for a proper session.

Later that Monday afternoon, the swell backs off a touch to 7ft but the wind swings onshore, making it a bit mushier. Still surfable, but the morning is the go.

The swell builds again for Tuesday morning, September 15th. We’re looking at 8ft of SSE swell with a period of 9 seconds. The energy is cranking – strong at 1038. But the wind is cross-shore, so it’ll be a bit lumpy. Still, there’s power there for the taking. This is the other one to keep an eye on, especially if you don’t mind a bit of chop.

After that, it fades into smaller, messier surf for the rest of the week. The energy drops right off, and we’re back to onshores and poor conditions through to September 21st. A flat spell, really. There’s a little bump of 4ft with clean winds on Friday morning the 18th, but it’s nothing to get too excited about. Then things shut down again.

Now, looking further out, there’s a pulse of energy for the 23rd of September. But before you get your hopes up – the wind is howling at 19 mph from the SSW, and it’s going to be a messy, lumpy mess. The swell is 6ft and the energy is moderate, but the conditions are poor. This one's looking more like a challenge than a treat. However, keep an eye on the afternoon of that Wednesday – the swell jumps to 8ft and the wind eases, but it’s still cross-shore. It could be a wild one, but the energy is very strong at 2435. That’s a lot of water moving. For the experienced crew, that could be interesting. For the rest of us, maybe a pass.

The last week of the outlook is a mixed bag. There’s a small clean window with a 4ft SSE groundswell on the morning of September 25th, but the wind is a bit cross. It’s not a standout, just a “maybe” session.

So, to sum it up: Your best bets are Monday morning the 14th and Tuesday morning the 15th. Anything else is a gamble. It’s a waiting game, but when it turns on, it turns on.
