The Lowdown
Alright, grab your board and come here. It’s Rusty, and I’m looking at what we’ve got for the next couple of weeks at Praia do Aventureiro.
Right off the bat, things are a little flat to start, with no surf worth paddling out for until Friday afternoon, the 11th. That first window is a bit iffy – there’s about 3ft of south swell, but it's a cross-on breeze messing it up. The water's sitting at 73°, which is a touch warmer than normal for this time of year.
The real hopeful moment arrives on Monday afternoon, the 14th. We’re looking at a clean 5ft SSE swell, and the wind goes completely glassy. That’s the standout. The combined swell energy hits 394 (moderate), and with the point break setup handling that southeast direction well, you’ll find some nice lines if you can get out. Just keep in mind that crowd factor – it’s a known spot and can get busy sometimes.
Tuesday the 15th stays clean in the morning with a 5ft SE swell and light offshore wind from the SW, which is a solid combo for this point. Wednesday the 16th is another beauty – 5ft SE swell, glassy conditions in the morning – you couldn’t ask for much better right now. The energy jumps to 631 by Wednesday, which is solid.
Things get a bit messier from Thursday the 17th through the following week. There’s some pulse here and there, but the wind turns onshore or cross-on more often than not, and the swell drops off. You get a few windows – like the 21st Monday morning with a glassy 4ft SSE, or the 22nd Tuesday morning with a glassy 4ft S swell – but nothing massive.
The last real standout is on Saturday, the 26th. A clean 6ft south swell, glassy conditions early, and the combined energy is 973 (strong). This is one for the experienced crew – over 5ft and creeping toward 7ft, so beginners might struggle. The paddle out should be easier with that longer 9-second period. The afternoon bumps up to 7ft with a longer 12-second period, but the wind goes cross-on, which will put some texture on the face. Still, a groundswell that size and direction can throw some power at this point break.
Overall, the best windows are the 14th, 15th, 16th, and that last chance on the 26th. First week is the safest bet; the second week gets more inconsistent with less reliable breaks.
Rusty.
