The Lowdown
Right then, let’s have a look at what’s on offer for Balneario Sao Jose over the next couple of weeks.
Truth be told, the next few days are pretty flat and ordinary. There’s a bit of small swell knocking around, but the wind’s all over the shop and the conditions are messy. Not much to get excited about. You’ll be waiting until Sunday the 26th of July before anything half decent shows up.
Sunday the 26th of July is the first real highlight. Early morning, it’s clear and glassy with a light NE breeze. The swell is only 2ft, but it’s a long-period southerly groundswell at 13 seconds, which gives it some real push and shape. The combined energy is moderate at 321. This is a beach/pier setup, so the long period might make it a bit straight, but with clean glassy conditions, it’ll be worth a paddle. The water temperature is 68°, which is pretty much dead average for this time of year.
The following Monday the 27th also has a glassy start with 2ft of south-east swell, but the period is a shorter 8 seconds, so it won’t have the same punch. It’s surfable, but nothing special.
The next real standout doesn’t come until Monday the 3rd of August. That morning, the wind is light and offshore from the north, making for clean conditions. The swell is 2ft from the south-southeast, but with a very long period of 14 seconds. That’s proper groundswell energy, and the combined energy is a solid 264. This is the best looking window in the whole forecast – clean, consistent, and that long period will wrap nicely. Expect an offshore breeze and clean waves, though the long period might mean longer lulls between sets.
The following morning, Tuesday the 4th of August, is also a cracker. The wind is dead calm, glassy, with a 3ft southerly swell at 12 seconds. That’s a lovely clean morning with moderate energy (287). This is another one to circle on the calendar.
After that, things drop off again. The wind turns onshore, the swell gets smaller and shorter period, and it’s back to ordinary conditions.
So, the best of the lot is Monday the 3rd of August and Tuesday the 4th of August. Both mornings have offshore or glassy wind, clean conditions, and solid, long-period groundswell. For a beach/pier spot, that’s as good as it gets in this stretch.
