The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Balneario Sao Jose.
Right now, we’re in a bit of a flat spell. There’s not much to get excited about for the first few days, but don’t write the whole forecast off just yet. The surf is small and weak to start, with combined energy barely cracking 100 (87 to 111). Things are quiet, but we’ve got a window of clean, offshore winds on the horizon that will make the most of what little swell we have.
Thursday the 16th is the first real bright spot. It’s not big, with a 5ft swell from the ESE, but the wind is glassy in the morning. That’s a major positive. Combined energy is a moderate 391, and with no wind to mess it up, the waves will be clean and smooth. It’s a good day for an intermediate surfer to get a few fun ones without the crowds being too crazy.
Friday the 17th and Saturday the 18th mornings are also worth a look. The swell drops to 4ft, but we’ve got a light offshore wind from the North. The period is a short 8 seconds, so it’ll be a bit choppy, but the clean conditions will make it surfable. Energy drops to 274 and 234, so it’s not powerful, but it’s a nice chance to get wet.
After that, the surf really fades away. We’re looking at a long gap of several days – from Sunday the 19th all the way through to Thursday the 24th – where the swell is tiny, mostly under 3ft, and the energy is very weak. It’s a blank run, and honestly, for this area, that’s not unusual when the swell window goes quiet.
Now, the real standout is a week and a half away. Mark your calendar for Tuesday the 28th. The morning session is the pick of the entire forecast. We’re talking a 5ft SSE groundswell with a very long period of 14 seconds, and glassy conditions. The combined energy is a massive 1136, which is strong and powerful. The wind is dead calm, so it’ll be perfect. This is excellent surf for experienced surfers only – it’s over the 5ft mark, so it’s not for beginners. The long period and size will make it a proper, powerful groundswell, best taken on a point or reef, but the beach here will still have some heavy, well-shaped walls. The water temp is sitting at 66°, which is about average for the time of year, so no major surprises there.
The 27th also has a glassy morning with 4ft S swell and 11 seconds, but the energy is 412, so it’s a more moderate, less powerful session. Still clean, but the 28th is the one to wait for.
The final week gets messy again with onshore winds and rain, so don’t get your hopes up for the 29th and 30th – the conditions look poor.
Stay patient, and be ready for that Tuesday morning. That’s the one.
