Prainha Surf Forecast and Surf Report

Alright, grab a coffee and listen up. It’s Rusty here, and I’ve been staring at the charts for your local stretch. The whole 16-day window is a bit of a mixed bag, but let’s get into it.

The water here at Prainha is sitting at 68°, which is a touch warmer than what you’d normally expect for this time of year. Not a major shift, but enough to notice when you’re paddling out.

For the first few days, it’s all pretty ordinary. Sunday the 30th and Monday the 31st have some small, clean waves coming from the east – around 3 ft to 3 ft – but the combined energy is weak (92 to 103). The wind is cross-off, so the surface is clean, but the swell is tiny and short-period at 8 seconds. It’s surfable, but you’ll be working for every little ride.

Tuesday the 1st starts off messy with a cross-shore wind, but the afternoon glass-off is a real treat. The swell bumps up a touch to 3 ft from the ESE, and the combined energy is moderate (121). Not a standout, but a nice little window for a sunset paddle.

Now, Wednesday the 2nd of September is where it gets interesting. The morning looks mint. The swell jumps to 5 ft from the SSE, with a moderate amount of energy slamming in (527). The wind is a clean cross-off from the south, keeping it all smooth. This is good for advanced surfers – the size is enough to get a decent drop, but it’s not out of control. The 8-second period means it’s a bit of a windswell, so it’ll be a bit crumbly, but the conditions are very good. This is the best on offer in the whole forecast.

The rest of the week and into the next is a tough watch. From Thursday the 3rd right through to Tuesday the 9th, the score is consistently poor. The wind is mostly onshore or cross-onshore, and the swell direction is a bit all over the place. There’s a glimmer on Friday the 4th morning with a 2 ft swell and offshore wind, but it’s tiny. The combined energy is weak (74).

We get another glassy moment on Thursday the 10th, but again, it’s just small, weak surf. The standout potential is gone.

The second week is a real struggle. Friday the 11th has a very interesting long-period swell (15 seconds) from the southeast, but it’s only 1.0 ft. The energy is barely there (83). For a point break or reef, a long period is a treat, but on a beach break like this, it’s just going to be weird and weak. The rest of the days are all poor, with onshore winds and lumpy conditions. The combined energy stays moderate at best (304 on the 14th), but the wind and chop ruins it.

Honestly, for this stretch of coast, a blank run like this isn’t unusual. The consistent spots are few and far between, and the forecasts can change. But for now, save your energy for Wednesday the 2nd of September morning. That’s your window. The rest is a waiting game.

Rusty.
