The Lowdown
Alright, this is Rusty.
Right off the bat, we’ve got some solid clean conditions on the cards for Praia do Aventureiro. It’s a beginner-friendly point break that’s very consistent, so there’s plenty to work with over the next few days. The water temp is about average for this time of year, nothing wild to report there.
The standout window is hands down Saturday morning, the 15th. We’re looking at a 7 ft S swell, 13-second period, with glassy conditions. That’s the pick of the bunch. The combined wave energy is solid at 1425 (moderate energy). That’s gonna be super clean and punchy for experienced surfers.
Thursday morning, the 13th, kicks things off with a clean 6 ft S swell, 12-second period, glassy offshores from the ENE. Combined energy is 1017 (moderate). It’s a nice warm-up, not as big as Saturday, but really lined up.
Friday morning, the 14th, also offers clean waves. The wind goes glassy from the WSW, with a 6 ft S swell hanging in there at 13 seconds. Energy drops a little to 982, but still fun.
Saturday afternoon goes to crap with an onshore ESE blow at 12 mph and a risk of thunderstorms – total write-off.
Sunday the 16th is a no-go too. Onshore wind all day and short period swell.
Monday the 17th might be worth a look early. Clean-ish cross-on wind from the NE at 3 mph, but the swell has dropped to 4 ft with that short 8-second period. The energy’s down to 185 (weak). It’s glassy, so it’s surfable, but very ordinary.
Then there’s a real dry spell from the 19th through the 22nd. The swell direction shifts, periods get short, and winds are messy. Not much to get excited about.
Sunday the 23rd afternoon sees a bit of hope. 4 ft S swell, 10-second period, glassy conditions from the WNW. Combined energy sits at 420 (moderate). It’s not pumping, but it’s clean.
Monday the 24th morning brings a glassy start with a 5 ft S swell, 10-second period, and combined energy of 745 (moderate). That’s a solid session for a Monday.
Tuesday the 25th morning also looks promising. Clean 4 ft S swell with a nice 14-second period (that’s a longer period, groundswell), glassy conditions from the east. Energy is 748 (moderate). This one’s going to have nice shape and long lines – best for the point setup here.
After that, the swell fades out through the end of the month. By the 28th, it’s tiny, 2 ft, with very low energy. Summer doldrums kicking in.
Overall, Saturday morning the 15th is your main event. Get it while it’s good.
Rusty.

A general guide to surfing at Praia do Aventureiro can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
