The Lowdown
Alright, Rusty here. Let's chew the fat on what's coming down the line at Praia do Aventureiro.
Right now, things are pretty ordinary. The surf is small and the conditions aren't doing us any favours. We’ve got a bit of a wait on our hands, but there’s some real quality on the horizon.
The water is sitting at a pleasant 73°, which is a touch warmer than you'd usually expect for this time of year – nice for a longer session.
The first real glimmer of hope is on Sunday the 20th. The morning is looking glassy with a 6ft east swell pushing through. The energy is moderate at (606), which should offer up some fun little peaks. The wind goes glassy, so expect it to be clean. That afternoon stays clean too, though the swell drops a touch. This is our first proper chance.
Then, after a few quiet days, the surf really starts to build. We’re looking at some serious groundswell arriving around Thursday the 24th and Friday the 25th. The swell direction comes from the south, with periods stretching out to 14 and 15 seconds. That's proper long-period energy, (1329) on the energy scale – that's strong. The problem is the wind; it's onshore from the east, blowing straight into the face. For a point break setup, an onshore wind is a killer and makes it look pretty average, even with that much power. For the experienced crew, there might be something to find, but it's not going to be pretty.
Now, the absolute standout of the whole run looks like the weekend of the 27th and 28th of September. Hold onto your board.
Saturday the 27th of September is the pick of the bunch for me. The morning kicks off with a 4ft south-southwest swell, building through the day. By the afternoon, we’ve got a 5ft south-southeast swell, but the magic is in the wind – dead glassy. The energy is pumping at (749). That right there is the recipe for some of the cleanest, most lined-up waves you'll see at this break all forecast. It’s a genuine standout.
Sunday the 28th of September morning is also looking very special – glassy again, with a 5ft south swell and (771) energy. That is prime. Unfortunately the afternoon gets blown out by a strong 25 mph cross-off wind, so the morning window is the one to chase.
After that, we’ve got some strong south swells continuing into Tuesday the 29th and even the 1st of October, but the wind becomes a bit more of a lottery with some cross-onshore and afternoon wind showing up. The 1st of October morning, however, is looking glassy again with a solid 5ft south groundswell – another potential gem if you’re flexible.
Keep in mind, this is a point break that's very consistent, so the long gaps between sets you get with these long-period swells shouldn't be an issue here. Just keep an eye on that wind direction; when it’s onshore, even the biggest swell is a washout.
Bottom line: There’s a lot of average in the near future, but the weekend of the 27th and 28th of September has the potential to be absolute magic. Get your sessions in early on those days.
Rusty.
