The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Praia do Aventureiro over the next couple of weeks.
Right now, the water’s sitting at a touch warmer than normal for this time of year, about 73°. That’s a nice bonus for the skin, but don’t get too excited about the surf just yet.
We’ve got a slow start. Thursday and Friday are pretty ordinary, with small, weak swells and poor conditions. Friday morning shows a pulse of 3ft from the east at 7 seconds, but it’s just surfable, nothing to write home about. The energy is weak (142). Not worth paddling out for.
The first real highlight kicks off Saturday, 22nd August, in the morning. We’ll see a clean 5ft south swell with a period of 8 seconds, and the wind is glassy from the west-southwest. The combined energy jumps to a moderate 349. For a beginner-friendly point break like this, those are some of the best conditions you'll get in this stretch. Good, rideable waves with no wind chop.
Sunday morning, 23rd August, is another glassy session. The swell holds at 5ft from the south, now with a longer 10-second period and solid energy (431). That’s a really clean, fun wave on offer, especially for the early birds. The afternoon gets messy with cross-onshore winds, so make the most of the morning.
Now, here’s where it gets interesting for the more experienced crew. From Monday, 24th August, through Wednesday, 26th August, a strong, long-period south groundswell fills in. We’re talking waves around 7ft to 8ft, with a period of 14 seconds, and energy readings soaring into the thousands. That’s proper power. The standout is Wednesday, 26th August, in the morning – glassy conditions, clean 6ft swell from the south with that long 13-second period, and excellent surf for experienced surfers. The energy is huge at 1366. This is the best session of the entire outlook, no question. The crowd profile at this break is ‘sometimes’, so expect some company, but it’ll be worth it. That long period will make for some beautifully lined-up waves on this point, but keep in mind the sets will be more spaced out.
After that, things back down quickly. The end of August and start of September look mostly poor, with onshore winds and weedy swell. There’s a brief glassy moment on the 30th, but it’s small and weak. A couple of days around the 3rd and 4th of September show another pulse of southerly swell (7ft to 8ft), but it’s accompanied by onshore wind and rain, making conditions poor. That’s a write-off.
So, to sum it up: the best windows are the glassy mornings on Saturday 22nd and Sunday 23rd for everyone, and Wednesday 26th August morning for the experienced lot. Don’t bother with much else.
Rusty.

Information about the Praia do Aventureiro Surf forecast

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.
