The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Praia do Aventureiro over the next couple of weeks.
First up, we're looking at a solid run of clean conditions to kick things off, but it gets a bit messy in the middle. The water is sitting at a balmy 74°, which is a good 4° warmer than usual for this time of year, so you’ll be in for a warm one.
Thursday morning, the 10th, starts us off with a clean 3ft swell from the south, with a period of 12 seconds. The wind is a light cross-off from the NNW at just 3 mph, making for some tidy lines. The combined energy is moderate (363). It’s a solid, if unassuming, start.
Friday morning, the 11th, is the real standout. We’ve got a 4ft south swell, but the period jumps to 14 seconds, and the energy is really starting to pump (600). The wind is absolutely glassy from the NNE at 3 mph. This is as good as it gets for a point break like this – clean, long-period groundswell groomed by offshore breezes. This is your window.
The weekend and start of next week get a bit sloppy. Saturday the 12th is a write-off, and Sunday the 13th has a decent 5ft pulse in the morning with glassy conditions, but the period is short at 9 seconds, so it’ll be a bit lumpy and weak. Monday the 14th gets blown out with onshore winds and a choppy 6ft swell.
We get a reset on Tuesday the 15th morning. The wind goes glassy again with a clean 3ft south swell at 11 seconds. It’s a small window, but it’s clean. Wednesday the 16th afternoon also looks tidy with a 2ft south swell and light cross-off breezes.
Now, looking ahead to the 17th of September, Thursday, we see a big jump in size. The swell hits 6ft, then 7ft in the afternoon, from the south. The energy is very strong (1235 and 1278). But the wind is cross-on from the ENE, and the period is a solid 12-13 seconds. This is a powerful, long-period groundswell, which is great for this point, but the wind will make it a challenge. It’s more of a big-wave day for the experienced crew.
The week after that looks small and inconsistent. There’s a gap of several days with no real recommendations. We get a bit of a clean-up on the 20th with a glassy 2ft swell, but it’s very ordinary. The real next chance comes on the 24th of September, Thursday morning. A 6ft south swell rolls in, glassy conditions, but the period is short at 8 seconds, so it’ll be a bit fat and weak. Then on the 25th of September, Friday morning, we see a powerful 5ft south swell with a very long 14-second period and massive energy (1250). The wind is a light cross-on, so it’s a promising but less certain prospect this far out.
So, the clear winner is Friday morning, the 11th. Get out there for that glassy, long-period south swell. The crowds are listed as "sometimes," so you might have some company, but with conditions like that, it’ll be worth it.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Praia do Aventureiro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
