The Lowdown
Alright, Rusty here again. Let’s break down Balneario Sao Jose for the next couple of weeks.
First week is a slow one. From Monday the 27th of July through the end of the month, the waves are tiny – mostly 1ft to 3ft – and the energy is weak (combined energy values between 68 and 166). Mornings are often glassy, which is a nice look, but the swell is too small and weak to get your heart racing. Water temp is 68°F, pretty average for the time of year.
The first real standout hits on Wednesday the 5th of August. Morning sees a 3ft South swell with a long period of 11 seconds, combined energy of 217, and dead calm wind. The report says “expect good surf conditions.” That’s a proper groundswell with clean shape. The crowd is “often” here, so you won’t be alone.
Thursday the 6th of August is even better. Morning has a clean 3ft South swell with offshore cross-off wind from the NNE and energy of 201. The afternoon bumps to 4ft from the South, glassy, and energy of 255. That’s the best session of the whole forecast – bigger, cleaner, and still moderate energy.
Sunday the 9th of August afternoon has a 4ft South swell, but the period is short at 7 seconds, so it’ll be a bit lumpy. The glassy wind helps, but it’s not as good as the 5th and 6th.
The second week goes downhill. The 10th and 11th of August bring onshore winds and rain, with choppy conditions. Not worth it.
Bottom line: circle Wednesday the 5th and Thursday the 6th of August. Glassy mornings, clean South swell, and the best energy of the run. The rest is a miss.
Rusty.
