Updates in hr min s Forecast update imminent
Righto, let’s have a look at what’s cookin’ at Balneario Sao Jose. It’s a beach and pier setup, exposed to the south-east swells, and it’s a spot that sees crowds often. Fairly consistent, but we gotta pick our windows.
The water temp is sittin’ right around 68°, which is bang on average for this time of year, so no surprises there.
We start off a bit average. Saturday the 4th has some chest-high 5ft S swell with a 10-second period, but it’s onshore and lumpy. Not worth paddlin’ out. Sunday the 5th though, that’s where it gets interestin’. The morning goes glassy with clean 5ft S swell at 12 seconds. That’s a nice groundswell, with moderate energy (712) and no wind. The sets will have some push, but the beach break might make ‘em a bit straight. Still, that’s the best look of the first few days.
Monday the 6th still has some clean waves in the morning – 4ft S swell, glassy, but it’s droppin’. From Tuesday afternoon onward, it gets chopped and messy for a few days. There’s a bit of a dry spell from the 7th through the 14th, with only tiny, weak surf and often poor conditions. Not worth gettin’ wet for.
Now, two standouts on the horizon. On Wednesday the 15th, we get a pulse of 5ft S swell with a long 13-second period and moderate energy (744). The wind is light cross-onshore, so it’s not perfect, but the size and period should offer some fun, cleaner lines at the pier if you can handle the crowd.
But the real gem lands on Saturday the 19th. A chunky 8ft E swell with an 8-second period and strong energy (1318). That’s big – only for the experienced crew. The morning looks glassy, with some clouds. That’s a heavy slab of water, and with that short period, it’ll be dumpy and powerful. Only the experts should be out. That’s your best wave of the whole 16 days, no question. It’s a long way out, so things can shift, but if it holds, it’s a ripper.
So to sum it: Sunday 5th morning for clean, mid-sized fun, and Saturday 19th morning for a big, expert-only hit. The rest is mostly small or messy.
Stay stoked.
