The Lowdown
Alright, Rusty here again. Let’s break it down for Balneario Novo Quintao over the next couple weeks, in good old feet and miles per hour.
It’s a slow burner. Water temp is 59°, a bit cooler than average for this time of year, so don’t forget a good wetsuit.
The first real chance to surf comes Monday the 14th of September. Monday morning you’ve got a small SSE swell at 3ft, period 8 seconds, wind just cross at 6 mph. The energy is weak at 256. It’s a marginal call, but if you’re itching, you might find something.
Tuesday the 15th is a bit better. Tuesday morning the swell is from the SE, 4ft, period 8 seconds, with a cross-offshore wind from the SW at 9 mph. The energy is moderate at 325. It’s clean, but still marginal. Tuesday afternoon drops to 2ft, so morning is the go.
Wednesday the 16th sees some more size. The morning has a 6ft swell from the south, period 8 seconds, with cross-offshore wind from the SW at 16 mph. The energy hits 637, the best of the early week. Still a marginal call, but it’s the pick of the early days.
Now, the real standout is Monday the 21st of September. That morning, we’ve got a 4ft swell from the east, period 9 seconds – a nice groundswell. But the big news is the wind: offshore from the WSW at just 3 mph. Glassy, clean conditions. The energy is moderate at 282. This is your window. The break is a beach and pier setup, and it’s inconsistent, so don’t expect a crowd every time, but when it’s this clean with the swell from the optimum direction, it’s worth the paddle.
After that, things go downhill. Thursday the 17th and Friday the 18th are poor with strong onshore winds. The weekend of the 19th and 20th is lumpy and onshore. Sunday the 20th has some 6ft east swell, but the wind is cross-onshore – not clean.
The second week is patchy. Tuesday the 22nd afternoon has a cross-offshore wind and 4ft east swell, but it’s marginal. Friday the 25th has size – 6ft – but the period is short at 6-7 seconds and the wind is onshore. Messy. Saturday the 26th morning might be a last chance: 5ft east swell, period 8 seconds, cross-offshore wind from the NW at 12 mph. Clean but marginal.
So, if you can hold out for Monday the 21st of September, that’s your best bet. Everything else is either small, windy, or both. For an inconsistent spot, that’s just how it goes.
Rusty.
