The Lowdown
Alright, grab a coffee and listen up. It’s Rusty here, giving you the straight story on our little slice of the coast.
We’re looking at a real mixed bag over the next two weeks. The first few days aren't really worth paddling out for—just dribbly little lines with onshore crud. It’s not until the first week of September that we start seeing any real potential, and the main event doesn’t show until the second week. The water is sitting at 72°F which is a touch warmer than normal for this time of year at Praia do Aventureiro.
For Saturday the 29th and into Sunday the 30th of August, the swell is tiny, around 3ft from the ESE, but the period is short at 7-8 seconds and the combined energy is weak (149). Saturday is a write-off with onshore wind and poor conditions. Sunday morning cleans up with a light cross-offshore S wind, making the tiny waves rideable, but it’s barely enough to get wet. Don’t get your hopes up.
Monday the 31st and Tuesday the 1st of September are similar. The onshore wind returns Monday, and even though Tuesday has a bit more energy, the 3ft ESE swell with a 9-second period is still mere knee-high stuff with mixed winds. It’s ordinary at best.
Now, Wednesday the 2nd of September gets interesting, but not for the right reasons. A strong SW wind kicks up to 30 km/h in the morning, and the swell jumps to about 6ft from the SW, but it’s a short 6-second period (267 moderate energy). The afternoon jumps to a heavy 10ft from the SSW with a combined energy of 1151; it’s got some grunt but that’s a lot of close-out chop and a fresh breeze. Honestly, this is looking more like a kitesurfer’s window than a clean paddle wave—it’s messy.
Thursday the 3rd holds about 6ft from the S at 9 seconds, but the wind is straight onshore by the afternoon, ruining any shape. Friday the 4th of September is our first little standout. The early morning looks glassy as glass—SSW wind is dead, just a breath of SSE breeze—and the swell is a clean 4ft from the SSE at 10 seconds. Combined energy is a moderate 309. That’s a fun, clean shoulder-high wave for the morning session before the onshores kick up by lunch. If you can, sneak out then.
From the 5th to the 7th, conditions drop off again. Light rain and moderate winds keep the surf messy and weak, mostly 2ft to 5ft with poor quality. Saturday the 5th and Sunday the 6th are a waste.
The big standout – Tuesday the 8th of September. This is the one to circle on your calendar. The Tuesday morning session is absolutely the best on offer in the whole outlook. The wind will be glassy, dead calm from the NNE (a very light touch), and we have a solid 5ft groundswell from the S with a long 11-second period. Combined energy is up at a solid 776. That’s good, clean, chest-to-head-high surf with proper lines pushing into Praia do Aventureiro. Crowds are possible here sometimes, so get out early. This is a point break, and that long period S swell will wrap in beautifully, giving you lined-up walls. Don’t miss it.
After that blessing, Wednesday the 9th and Thursday the 10th go downhill fast with onshore wind smashing the 6ft swell into chop. The 8-second period just won’t hold up. Friday the 11th through to the 13th of September we’re back to small, weak, glassy mornings with around 2ft to 3ft from the ESE. These are clean but tiny—good for a longboard and a bit of relaxation, not for any excitement. Overall energy by the 13th is down to 94, which tells you just how limp it is.
Right, that’s what we’ve got. Don’t waste your time on the early days. Hit the glassy dawn of Friday the 4th if you must, but make sure you’re out for that Tuesday the 8th of September. It’s the one.
Stay stoked.
Rusty.

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.
