Table - best surf conditions forecast for Balneario Sao Jose over the next 16 days.
G’day, it’s Rusty. Let’s break down what’s in store for Balneario Sao Jose over the next couple of weeks.
We’ve got a quiet start with some small, ordinary waves on Friday the 10th – the energy is weak, and it’s nothing to get excited about. Things pick up Saturday morning the 11th with 4ft of SE swell, a 13-second period, and glassy conditions. The wind is dead off and the water’s 67°, about average for this time of year. That’s a clean, fun session for intermediates. Sunday morning the 12th stays clean with a 3ft SE swell and cross-off wind – still a good bet.
The real standout is Tuesday morning the 14th: 6ft of SSE groundswell, 11-second period, glassy, and strong energy. That’s a ripper morning with clean, powerful waves. Wednesday the 15th is nearly as good with 5ft SE swell, glassy, and very good conditions. Thursday the 16th keeps the run going with 5ft SE swell, glassy, and solid energy. These three mornings are the best in the window – clean, punchy, and well-shaped.
After that, the swell drops to 2ft to 3ft over the weekend of the 18th and 19th, with only average energy. There’s a dry spell from the 20th to the 22nd with mostly poor conditions and weak energy. Then a late pulse on Thursday the 23rd brings 6ft SSW swell, but the wind is cross-on and the period is short at 9 seconds, so it’s messy. The week-two highlight is Friday the 24th: 5ft SE swell, glassy, and very good conditions – promising, but it’s a long way out.
Crowds are often around, so expect company on the clean days. This is a beach/pier setup, fairly consistent, and exposed to the SE swell. When the swell gets over 5ft, beginners might want to sit it out, but intermediates will have a blast.
Stay stoked, and I’ll see you out there.
Rusty.
