The Lowdown
Alright, Rusty here. Let’s chat about what’s coming up along this stretch.
The first few days are a mixed bag, but there’s a good pulse on the way. Praia do Porto (beach/jetty) is where we’re looking. Water temp is right around 66°, which is normal for this time of year, nothing crazy.
Monday the 24th afternoon is the opening act. We’ve got a clean 8ft swell from the south, with a 14-second period – that’s a proper groundswell. The cross-off wind from the SSE will keep things tidy. The energy reading is a massive 2507 (very strong). This is for experienced surfers only; it’s powerful and moving fast. The long period means it might be a bit straight on the beach, but there’s plenty of push.
Tuesday the 25th morning drops to 6ft south swell, but the wind goes cross-on from the NNE – not ideal. Afternoon is blown out with onshore wind. Wednesday and Thursday are total washouts with strong onshore breezes and messy surf.
Friday the 28th is a short-period windswell (8 seconds) and choppy. No thanks.
Saturday the 29th morning is a nice change. We’ve got 6ft from the ENE with a 9-second period, and a gentle offshore breeze from the SSW. That means clean, glassy waves. The energy is a modest 479 (weak), but it’s fun and user-friendly for the beginner-plus crowd. That’s your best small-wave session early on.
Sunday the 30th and Monday the 31st are small and marginal, though Monday afternoon goes glassy with 4ft – a nice little evening paddle if the tide works.
Now, the big one: Tuesday the 1st of September morning. A solid 10ft south-southwest swell, 10-second period, with a gentle offshore wind from the SW. That’s excellent for experts. The energy reading is 3353 (very strong). This is the standout of the whole 16-day stretch – clean, powerful, and pushing hard. Too big for beginners, but the experienced crew will be stoked. The afternoon stays clean but drops to 8ft.
After that, it fades. Wednesday the 2nd through the end is mostly onshore junk, small swell, and poor quality. There’s a little lift around Saturday the 5th and Sunday the 6th with some clean offshore wind and 5-7ft south swell, but it’s inconsistent and rainy. The last real highlight is Monday the 7th of September morning – 6ft from the SSE with a 12-second period and glassy conditions. That’s a very good session, clean and lined up, but it’s a short window.
So, calling it: Monday the 24th afternoon is the first standout for experts. Tuesday the 1st of September morning is the best of the whole run – big, clean, and powerful. If you want something smaller, hit Saturday the 29th morning.
Stay salty,
Rusty.
