The Lowdown
Alright, Rusty here. Let’s cut through the noise on Balneario Novo Quintao. Honestly, the first week and a half is rough. We’re looking at a long stretch of nothing but messy, blown-out conditions before anything decent shows up.
Monday the 14th kicks off with a small 3ft SSE swell at a short 8 seconds. The wind is cross, creating a light chop, and the combined energy is moderate (237). It’s barely worth a look. It just gets worse through Tuesday, Wednesday, and Thursday as onshore winds pick up and chop the swell to bits. By Friday the 18th, we’ve got fresh cross-onshore winds at 18 mph and a messy 5ft wave – pure junk. That run continues all the way to Sunday the 21st.
Now, on Monday the 21st of September, the tide turns. Morning looks good. A 5ft swell from the east with a solid 9-second period, and a light cross-offshore breeze from the southwest. That’ll clean the surface right up. The combined energy is moderate (317). It’s not big, but after a week of trash, this is the clear standout. It’s a beach/pier setup, water temp is about average for the season, and crowds are only “sometimes” a factor. This is your best bet.
We get another small window on Thursday the 24th. The morning brings a clean 4ft easterly swell with a light offshore wind from the west-northwest. Combined energy is moderate (290). It’ll be glassy and clean, perfect for a smooth session. The afternoon is similar, just smaller at 4ft.
After that, the swell fades fast. The last few days of September drop back into poor, onshore conditions with nothing to write home about.
So, the clear winner is the morning of Monday the 21st – cleanest conditions with a nice east swell and light offshore wind. Thursday the 24th morning is a solid backup. The rest of the time, honestly, with all that cross-onshore wind and chop, it looks more like a kiteboarding setup than a paddle session. Keep the faith – forecasts can change.
Rusty.
