The Lowdown
Alright folks, Rusty here with a look at what's on offer at Balneario Sao Jose. Gotta be straight with you – it’s going to be a bit of a slow grind for a while. The next week or so is mostly small and messy, but there is a little window of clean, fun waves to aim for later on. Hang in there.
The first few days are pretty weak. Monday the 14th is a non-starter with small, onshore 5ft S/SSE windswell – just not enough to get excited about. Tuesday afternoon the 15th looks a little better; we get some glassy conditions with 3ft S swell, which is the best call for the first few days if you can sneak out.
We've got a long stretch of poor conditions from Wednesday the 16th through to Friday the 18th. The swell is there but so is the wind, making it choppy and unappealing.
Now, there is a glimmer. Saturday the 19th brings a jump in size to 6ft from the ESE, but it's a short-period wind swell and the wind is still cross-shore. It’s more of a windsurfing setup than a clean paddle day.
The real standout comes Sunday the 20th and Monday the 21st. Sunday we get a clean 5ft ESE swell with a cross-offshore breeze – that's a solid, surfable day. But Monday the 21st is the one to circle. That morning, with a 4ft ESE swell, combined with a clean cross-offshore wind, will be the best quality of the whole outlook. The afternoon cleans up even more with a proper offshore NNW wind and 4ft ESE swell. This is your window, folks. It won't be huge, but the shape should be fun.
After that, the energy drops off quickly. From Tuesday the 22nd onward it's back to tiny, weak waves and mostly onshore winds. There's a couple of glassy mornings around the 24th and 27th, but with waves under 3ft, it's strictly longboard or minimil stuff.
So, bottom line: don't hold your breath for the first week. The highlight is definitely Monday the 21st – aim for that.
