The Lowdown
G’day, this is Rusty. This outlook is for Praia do Aventureiro, a point break near the sub-region of Praia-do-Aventureiro.
Alright, let’s call it what it is: the next few days are pretty flat and ordinary, but there’s a pulse of solid south swell lurking in the back half of the window that’s got my attention. The water here is sitting at 72°, which is a touch warmer than normal for this time of year, so that’s a pleasant surprise.
The immediate scene is weak. Wednesday morning the 19th is glassy, with a tiny 3ft east-southeast swell, but it’s only 7 seconds short and the energy is barely a whisper at 98 (combined energy). Wednesday afternoon fades further. Thursday and Friday mornings are glassy, but the swell is small and period is short, so it’s mostly a flat spell. Friday afternoon gets a clean wind from the south-southwest, but the swell is only 3ft—still not much to work with.
Saturday morning the 22nd is where things start to wake up. Clean cross-off wind from the south-southwest, and the swell jumps to 5ft from the south, 8 seconds, with moderate energy (307). That’s surfable and a decent chance for a beginner-friendly wave, but it’s not a standout. Saturday afternoon gets a bigger 5ft south swell, 10 seconds, and strong energy (515), but the wind goes cross-shore, so it’s a bit messy. Sunday the 23rd is glassy in the morning, but the swell drops to 4ft from the south.
Now, here’s the real story. Monday the 24th through Tuesday the 25th sees a proper south groundswell arrive. Monday morning has a 5ft south swell, 13 seconds, and energy already at 826 (moderate to strong). Monday afternoon it builds to 7ft, 14 seconds, and energy hits 1949—that’s strong. Tuesday morning holds 7ft, 14 seconds, with 1948 energy. But the wind is cross-on or onshore from the east, and the swell is large enough that it’s more for experienced surfers. The period is long, meaning better shaped waves, but at a point break like Praia do Aventureiro, that long-period groundswell will wrap in nicely. The downside is the onshore wind messes up the surface, so it’s not clean.
The standout moment is Wednesday morning the 26th. Glassy, a 4ft south swell, 12 seconds, and moderate energy (539). That’s clean, good shaped waves, and manageable size. That’s the one to target. Thursday the 27th is smaller and glassy but not as punchy.
The end of the window is interesting. Monday the 31st of August starts with a glassy 3ft south swell, 11 seconds, and good energy (382), then Monday afternoon glassy conditions bring a 6ft east-southeast swell, 7 seconds, and energy at 535. That’s a big height but short period, so it’s more walled-up and bouncy. Tuesday September 1st morning is glassy, 5ft east-southeast, 9 seconds, energy 419, and that’s a solid, clean option. And then Thursday September 3rd morning looks promising: a clean cross-off from the south-southwest, 6ft south swell, 13 seconds, and energy at 1062—that’s strong and clean. That’s a standout for the far end of the forecast, but it’s a long way out, so treat it as a potential.
Crowds at this spot can be around sometimes, so don’t expect an empty lineup, especially on the cleaner days.
Best bet: Wednesday morning the 26th is the golden window—clean, glassy, and a solid 4ft south swell. Tuesday September 1st morning is also a ripper. Thursday September 3rd morning is a far-off promise of clean, strong south swell.
Stay stoked.
Rusty.
