The Lowdown
G’day, Rusty here. Let’s break down what’s on the cards for Praia do Aventureiro. Classic point break, and the next couple weeks will test your patience, but there’s one proper session that’ll make it all worth it. Water temp’s about normal for the season—no surprises there.
Thursday the 20th is a bust. 2ft of east slop, weak energy around 45, and poor conditions. Don’t bother. Friday the 21st picks up a touch—3ft from the east with a light cross-off breeze in the morning (145). Surfable, clean, but pretty ordinary. The arvo gets blown out with a stronger cross-off.
Saturday the 22nd is where the south swell starts to roll in. 6ft from the south, energy jumping up to 555-713. Morning is a bit messy, but the afternoon cleans right up with light cross-off air and a 10-second period. This is the first good one—the point should be working nicely.
Sunday the 23rd is junk. Swell drops to 5ft, but the wind turns onshore and stays there. Bumpy and ugly. Monday the 24th gets bigger—7ft to 8ft from the south, with a 13 to 14-second period and four-digit energy (1344-2739). But it’s raining, cross-onshore, and choppy. Too messy, and at that size, it’s expert territory.
Then comes the gem: Tuesday morning, the 25th. Glass, calm, dead wind. Swell holds at a solid 8ft from the south, with a long 14-second period and energy at 2247. This is the best of the whole run—clean, powerful, and the point will be working. It’s big, so only for the experienced crew, but if you’re up for it, this is the one. The arvo turns onshore, so get out early.
The rest of the week fades. Wednesday the 26th arvo goes glassy again with 5ft from the south (1329)—clean and fun, but not as strong. Thursday the 27th is back onshore. Friday the 28th has a glassy morning with 3ft from the south-southeast (432)—clean, fun, nothing epic. Then it drops off hard.
From Saturday the 29th through to Tuesday the 1st, it’s weak—waves between 2ft and 2ft, poor conditions, energy under 200. A few clean windows, but not worth the paddle. Wednesday the 2nd tries to pick up, but it’s onshore and messy.
Now, skipping ahead—Thursday the 3rd and Friday the 4th of September look promising. Thursday morning is glassy with 6ft from the south-southeast (445), and the arvo goes clean with a cross-off breeze. Friday holds 5ft to 6ft from the southeast, clean with light cross-off. Not as big as Tuesday the 25th, but clean and consistent—a good way to finish.
The standout is Tuesday the 25th. Plan around that. There are gaps of a few days where it’s flat or junk, so be patient. When the south swell and clean wind line up, this point is special.
Rusty out.
