The Lowdown
Alright, folks. Rusty here. Let’s have a proper look at what the ocean’s got cookin’ for us at Praia do Aventureiro. It’s a bit of a slow burner this time around, so don’t be expectin’ perfection straight away.
Right off the bat, the first few days are a write-off for any decent surfing. From Saturday the 12th through to Monday the 14th, we’re lookin’ at poor conditions with cross-onshore winds messing with the surface, and the swell is tiny or just messy. Not worth paddlin’ out for.
Things start to look up a bit on Tuesday the 15th. The morning is still marginal, but by Tuesday afternoon, the wind swings cross-offshore from the SSW at 15 km/h, cleaning things right up. We’ve got 3 ft of swell coming from the SSE with a period of 9 seconds. The combined energy is at 316 — moderate, but nothin’ to get too worked up about. Still, it’s a clean wave after a few days of junk.
Now, here’s where we get the first real standout. Thursday morning, September 17th. The wind goes totally glassy from the NE at just 5 km/h. The swell pushes up to 5 ft from the south, with a period of 9 seconds and combined energy of 468 — moderate to strong. That’s a clean, fun-sized wave for a point break like this. The water’s warmin’ things up too — sittin’ at 73°, which is a touch warmer than normal for this time of year. That’s a treat for the skin.
Friday the 18th is another good call. Morning is glassy again with the same ENE breeze, 4 ft of south swell (11-second period), and energy at 551. That’s a solid, clean session. The afternoon holds cross-offshore winds too, so you could make a day of it.
There’s a bit of a lull over the weekend and into Monday the 21st — small, ordinary, or poor conditions. But we get another gem on Thursday morning, September 24th. Glassy conditions again, with 5 ft south swell, 8-second period, and combined energy of 535. Moderate-to-strong energy, clean glass, and it’s a point break so the period won’t straighten it out too much.
The last real highlight lands on Sunday morning, September 27th. Glassy winds from the SE at 5 km/h, 4 ft of south swell with a long 12-second period, energy of 643 — strong. That long period will give you some proper groundswell shape and good power, perfect for this point. Just be aware, with the deep water and long-period swell, the sets will be a bit wider apart, but you’ll have time to paddle out.
Overall, the best sessions are gonna be the mornings of September 17th, 18th, 24th, and the 27th. Get on ’em if you can. The point handles the south swell well, and when it’s glassy, it’s a dream for a beginner-to-intermediate wave. Crowds might pop up sometimes, so bring your patience.
Signin’ off. Stay salty.

Information about the Praia do Aventureiro Surf forecast
The above surf forecast table for Praia do Aventureiro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Aventureiro can be found by selecting the local surf guide option on the grey menu. Our Praia do Aventureiro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Praia do Aventureiro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
