The Lowdown

Alright folks, Rusty here. Let’s see what’s happening at Balneario Sao Jose.

To be honest, the next week and a half is pretty grim. We’ve got days of tiny, weak waves and dodgy wind, with a lot of “poor surf conditions” in the forecast. The water temp is sitting at 68°, which is pretty much normal for this time of year, so at least you won’t need a thick steamer. The first real glimmer of hope comes on Saturday, the 1st of August, when we get a pulse of 5ft easterly swell. It’s a short period (7 seconds) and the combined energy is moderate (458), but the morning is glassy – zero wind. That’s the standout session of the first week.

After that Saturday morning, it fades back into small, onshore junk for days. There’s a long gap with no real recommendations until we get into the second week.

Now, the real firecracker is shaping up for Thursday, the 13th of August. The morning looks absolutely prime. We’re looking at 6ft of swell from the SSE, with a 10-second period and a combined energy of 934 – that’s strong wave energy. More importantly, the wind is glassy, dead calm. This is the best on offer by a long shot. It’s a solid, clean swell with good energy, but at 6ft, it’s getting into the territory where beginners might find it a bit much. The break is a beach/pier setup, so with that SSE direction, it should line up nicely. The crowds are often an issue here, so get out early to claim your spot.

The week before that also has some moments. Wednesday the 12th of August morning has a glassy 5ft swell from the south (energy 582), which is a solid offering. Friday the 14th of August morning also has a clean 4ft (energy 520) with glassy conditions. But the 13th is the one to circle on the calendar. Remember, all this long-range stuff is promising but less certain, so keep your fingers crossed.

It’s a tough start, but it looks like it’ll come good. Stay patient.

Rusty.
