The Lowdown
G’day, Rusty here. Let’s break down the surf at Praia do Aventureiro. It’s a point break that’s great for beginners and very consistent, but we’ve got a slow start before it fires.
The first few days are a dud. Sunday the 16th has 6ft from the ESE, but a 25 km/h onshore wind is wrecking it. Wave energy is moderate (561), but it’s poor. Monday the 17th through Tuesday the 19th are mostly onshore, choppy, and ordinary. You’re waiting nearly five days for anything decent.
Wednesday the 19th morning, the wind goes glassy and there’s a clean 4ft ESE swell. Low energy (150), but it’s clean and rideable. Thursday the 20th morning is similar – glassy, 2ft. Fun on a longboard. Friday the 21st morning has clean cross-off wind and 4ft from the E. Ordinary but okay.
Saturday the 22nd morning is your first real highlight: dead calm, glassy, with 4ft of S swell. Short period, but clean and fun for beginners.
The big stuff hits from Sunday the 23rd. That morning is glassy with 5ft from the S, long period of 12 seconds, and strong energy at 698. Monday the 24th morning is the standout: 7ft of S swell, 12-second period, and a clean cross-off wind. Energy is pumping at 1355. That’s expert-only territory. Tuesday the 25th morning has 8ft from the S, even more energy at 1654, but heavy rain and cross-on wind. Still huge and powerful.
After that, it’s back to onshore junk from Wednesday the 26th on. The last clean window is Sunday the 30th afternoon – dead calm, glassy, with 2ft from the E.
Water temp is 72°, a touch warmer than usual, so a spring suit is fine.
The absolute best session is Monday the 24th morning: 7ft of S swell, clean wind, and serious groundswell power. That’s the one to chase.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
