The Lowdown
Alright, crew, Rusty here. Checking the charts for Balneario Sao Jose, and it's a tale of two weeks. A slow start, then a solid finish.
First up, nothing doing until Friday the 24th. The water is sitting at a normal 67°, nothing unusual for this time of year.
Friday morning the 24th, we get our first look. A little 3-foot swell from the S, short period. Nothing special, but the wind is glassy. Dead calm. That's a huge plus for this beach and pier setup. Wave energy is moderate (213), but it'll be a fun little grovel. Friday afternoon, that offshore wind from the N kicks in, cleaning it up even more. Expect some company on the pier, it gets "often" crowded here.
Saturday the 25th is the real winner of the first week. The swell picks up to 4 feet out of the SSE, still a bit short period but with glassy, offshore winds in the morning (276 energy). That’s clean, fun surf. The swell direction is close to the optimum SE, so the setup should work.
Now, here's the standout. Wednesday the 5th of August looks proper. A 4-foot S swell, but the period jumps to 12 seconds. That's a real groundswell with some punch behind it. You can see the energy has ramped up (480). Light cross-offshore winds from the NE will have it looking clean. This is the best session on the board for the more experienced surfer.
The rest of the forecast is a mix of small, average swells and onshore chop. There's a pulse of longer period swell in early August, but it comes with tricky winds. The first week is quiet, the second week has a couple of options, but Wednesday the 5th is the day to circle.
Stay patient.
Rusty.
