The Lowdown
Alright folks, Rusty here with a look at what’s on the table for Praia do Aventureiro over the next couple of weeks. It’s a bit of a slow burner, but trust me, there are some absolute gems coming.
We kick off with a rough patch. Saturday the 12th and Sunday the 13th look pretty sad – small, weak swell and onshore wind messing things up. Not worth paddling out for. We’ve got a few days of quiet waves to wait through before the magic starts.
Monday the 14th is where it gets interesting. The light rain isn’t ideal, but we’ve got glassy conditions on the morning with a clean 4ft swell pushing up from the SSE at an 8-second period. Combined swell energy is moderate (271). It’s not huge, but it’s clean and the break is very consistent, so it’s a good one for the beginners getting their feet wet. Wind stays light and cross-off in the afternoon, keeping things tidy.
Tuesday the 15th sees the swell building a touch to 5ft from the SE, still a short period (8s), but the combined energy jumps to a moderate 448. With light cross-off winds it stays clean, offering fun waves throughout the day.
Wednesday the 16th is still clean with a cross-off wind, swell dropping to 4ft but period lengthening to 9 seconds. Combined energy sits at 399. It’s surfable, but nothing to go crazy over.
Now, Thursday the 17th – this is a standout. We’ve got a glassy morning with a clean 5ft swell from the S and a long 13-second period. That’s groundswell, folks, meaning proper shape and energy. The combined swell energy hits a very solid 893. The break is a point, so this longer period stuff will wrap in beautifully. This is the best session of the first week. Expect very good conditions. Crowds can be *sometimes* around here, but it’s worth it.
The next few days are a mixed bag of smaller swells and onshore winds. Not much to yell about until the 21st, when we get a clean 4ft ESE swell with 8-second period. Glassy and cross-off options give you a chance for a fun session.
We then hit a lull with small, messy waves and strong winds on the 22nd. Not recommended.
Friday the 25th of September – this is the big one. The morning is crystal clear, calm winds, and a solid 7ft swell from the SSE with a 14-second period. The combined energy is a powerful 1937. This is for experienced surfers only – over 8ft is for experts, and this is close. The point break setup will handle this long-period groundswell perfectly, offering excellent, powerful waves. The water’s been about average for this time of year. This is your long-range standout – circle it.
The weekend of the 26th and 27th cleans up with cross-off and glassy winds, with dropping swell (5ft to 4ft) but still a solid 12-13 second period. Good energy (663-674) and clean conditions to finish the run.
So, the two to aim for: Thursday the 17th for the best all-round conditions and Friday the 25th for the serious power. Everything else is filler.
Rusty.
