The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Balneario Sao Jose over the next couple of weeks.
It's a bit of a slow start, I won't lie. The first few days are pretty flat and messy. Thursday the 23rd and Friday the 24th are a write-off with tiny, weak waves and cross-shore winds. You're not missing a thing. The real story starts to turn around on Saturday the 25th. We've got a clean little pulse coming in from the SSE at 4ft, and the wind goes glassy. That's a proper dawny right there. The wave energy is moderate (245), so it's got a bit of push, but it's still small enough for most. The water is sitting at 68°, which is about average for this time of year, so no surprises there.
Sunday morning the 26th drops in size to 2ft, but the swell period jumps to 13 seconds. That's a long-period groundswell, which means it'll have better shape and more grunt, but on a beach break like Balneario Sao Jose, it might be a bit too straight. Still, with glassy conditions, it's a fun little session if you're selective.
After that, we hit a proper flat spell. From Monday the 27th right through to the end of July, it's tiny, inconsistent, and not worth the paddle. A few glassy mornings but the waves are just too small. The wind picks up strong from the SW on Thursday the 30th, making a mess of things.
Now, August kicks off with a bit more promise. The 3rd and 4th of August are looking like the real standouts. Monday the 3rd has clean, glassy conditions with a 4ft to 4ft swell from the SSE. The combined wave energy is solid (325 to 359), and the 11-second period means nice, lined-up waves. The wind is glassy both mornings and afternoons. This is the best window we've got. The break is fairly consistent, so you can expect plenty of waves. Keep an eye out for crowds though, as it can get busy.
After that, the swell drops off again through the 5th, 6th, and 7th, with smaller, more ordinary conditions. The long-range stuff on the 7th looks a bit weak and short-period, so don't get your hopes up.
So, to sum it up: Saturday the 25th is a nice little warm-up, but the real gem is the Monday and Tuesday of the 3rd and 4th of August. That's your window. Get on it.
Rusty.

Information about the Balneario Sao Jose Surf forecast
The above surf forecast table for Balneario Sao Jose provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Balneario Sao Jose can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Balneario Sao Jose may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
