The Lowdown
Alright, grab your board and listen up. It’s Rusty here, and I’m lookin’ at the next couple weeks at Praia do Aventureiro. This is a point break, so it’s got that mellow, rolling vibe in its DNA.
Alright, let’s be real, the first few days are a write-off. We’ve got a bit of a gap here. Sunday the 16th and Monday the 17th are junk. The wind is onshore and messy, and while there’s some swell, the quality is just not there. You’ll be fighting a bumpy, gutless ocean.
Tuesday morning the 18th is our first real glimpse of hope. The ocean goes totally glassy, and we’ve got a 5ft swell rolling in from the east. The combined energy is sitting at a moderate 518, which is a solid pulse for this spot. This is the kind of morning you set the alarm for. The water’s a touch warmer than normal for this time of year at 72°F, so you can probably ditch the thick rubber.
Then it gets skinny again for a few days. Wednesday and Thursday are small and weak, with combined energy dropping into the low hundreds and even below 100. It’s barely dribbling. Friday the 21st has another glassy morning but with only a 3ft swell, so it’s just a fun little waist-high bounce for the loggers.
The real standout, and I mean the big one, is the window from Monday the 25th through Thursday the 28th. This is groundswell country. We’re getting a long-period S swell starting to show up on the 23rd, but it’s the early week that fires. Tuesday the 25th afternoon, the ocean cleans up with a light offshore wind, and you’ve got a solid 7ft S swell with a 13-second period. The combined energy is pumping at 1336 – that’s a lot of juice. This is for experienced surfers only; that size over 5ft can be a handful for beginners. It’s a point break, so that long-period groundswell will wrap in nicely, giving you those long, clean lines. This is the best on offer.
Wednesday the 26th and Thursday the 27th hold that swell, with energy staying well over a thousand. Thursday morning the 27th is glassy as a mirror with a 5ft S swell at 13 seconds – a very clean, powerful option for the crew that knows what they’re doing.
After that, the swell backs off into the end of the month. The 30th and 31st offer some small, clean waves in the 3ft to 5ft range, good for a longboard if you’re jonesing, but nothing compared to that main event.
This spot is very consistent, so don’t let the flat start fool you. It tends not to stay poor for long. The 25th through the 27th is the call. Get out there.

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.
