Balneario Sao Jose Surf Forecast and Surf Report

Alright, let’s get into it.

To start, the surfing this week is a bit of a mixed bag. We’ve got a pulse of energy coming through, but it’s not all gonna be clean. The water is running a touch warmer than usual for this time of year, which is always nice for the dawn patrol.

Our first real call is for Friday afternoon, the 14th, down at Balneario Sao Jose. It’s a beach and pier set-up, and it’s going to be the standout of the first stretch. We’re looking at chest to head-high surf, around 5ft, with that swell coming from the SSE. What makes it special is the wind – it’s glassy, dead calm, and the period is a solid 13 seconds, so there’s some proper grunt behind it. The water is a pleasant 69°F, and the overall energy is moderate at 696. This is the one to get out for if you can. The conditions are gonna be super clean, making it a really fun option.

Saturday, the 15th, is a step down. The swell bumps up a bit to 6ft in the morning, but the wind swings around to a light cross-onshore, which is going to put a few bumps on the face. It’s still surfable, but it’s not going to be as crisp as Friday. The afternoon drops off a touch to 4ft.

Sunday, the 16th, sees the swell period shorten right down to 8 seconds. That’s a sign of shorter-period windswell. The size is still there, around 6ft to 6ft, but with onshore winds, the quality drops off. The morning is a bit cleaner but has some cross-shore wind. The afternoon looks choppier. This is more of a fight than a fun session.

Monday, the 17th, the wind does us a favor and goes dead calm in the morning. There’s still 6ft of fun swell from the ESE, with a 9-second period. It’s glassy and clean, but a little less organized than Friday. By the afternoon it gets a bit messy.

From Tuesday the 18th through to the end of the week, things get pretty small and weak. We’ve got a handful of days with waves under 3ft. The energy drops right off, with numbers down in the 58-108 range, which is pretty weak. There are a couple of mornings with glassy conditions on the 18th and 19th, but the waves are tiny, in the 2ft to 4ft range. It’s really a time to dust off the longboard or find something else to do. There’s a decent gap of a few days here where the surf is pretty lackluster.

Looking into the following week, there is a pulse of energy expected around the 24th and 25th. It’s promising but a long way out, so keep an eye on it. The 24th of August looks like it could be solid with 8ft of S swell at a longer 13-second period, and the energy numbers are strong at 3228. The wind is light, too. Then on the 25th, the morning looks particularly interesting. It’s still a week and a half away, so treat it as a “could be good” rather than a certainty. There’s also a glimmer of hope on the 29th, with a clean morning and a bit of long-period groundswell at 13 seconds. But again, that’s a long way off.

In the meantime, keep your head on a swivel for those clean windows when they pop up.
