The Lowdown
Alright folks, Rusty here. Let’s see what’s cooking for the next couple of weeks.
We’re looking at a pretty drawn-out run of small, ordinary surf, with a real standout window for the experienced crew around the 7th of September. Before that, you’ll be doing a lot of waiting.
The first real shot at anything is on Tuesday, 1st September. It’s small, with waves around 3 ft from the ESE, but the Tuesday afternoon session is a beauty with glassy conditions. The combined swell energy is moderate (223). It’s a beginner-friendly point break, so it’s not going to fire, but for a quiet paddle, that’s your best early week option.
Things get a bit more interesting on Thursday, 3rd September, with a solid 5 ft SSE groundswell (11-second period). The energy is strong (514), but it’s cross-on shore in the morning, so it’ll be a bit lumpy. That’s the pattern for a few days—decent swell but messy wind.
Then we get to the real standout. Monday, 7th September. The swell pumps up to 8 ft from the S, with a 11-second period. The combined energy is very strong (1483). The wind is light and offshore in the morning, glassing it up. This is clean, powerful, and about as good as it gets for the experienced surfer at this point. It’s big, over 8 ft, so this is for experts only. The afternoon stays clean with offshore wind and 7 ft sets. This is the one to circle on the calendar. Tuesday the 8th is still solid at 6 ft, but the wind turns cross-on, so it’s not as clean.
After that, the swell drops and we get into a run of small, ordinary waves. The morning of Friday, 11th September is a nice surprise—flat calm, glassy conditions with 4 ft ESE swell. The energy is moderate (273). It’s a nice little window for a relaxed session. Saturday the 12th morning is also clean with 4 ft, but the wind stays light and cross-offshore.
Overall, the water temp is about average for the time of year. The first half of the week is a waiting game, but the 7th is a proper strike for the big-wave crew. For the rest, it’s small, clean, and mellow.
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.
