The Lowdown
G’day, Rusty here. Let’s chew the fat on what Praia do Aventureiro’s got lined up over the next couple weeks.
Right now, it’s pretty ordinary. The first few days are blown out with onshore wind and the swell’s not doing anyone any favours. You’ll be hanging tight till Tuesday morning, September 1st, before there’s even a chance to paddle. That morning, the wind goes glassy, with a little 3ft swell out of the ESE at 9 seconds. The water’s a touch warmer than normal for this time of year at 73°. It’s surfable, but honestly, the energy is weak and it’s real ordinary – just something to wet your line.
The real standout, and I mean the one to circle on the calendar, is Wednesday, September 2nd. That morning, a solid 8ft southerly groundswell (11 seconds) rolls in with light offshore cross-off wind from the SSW. The combined energy jumps way up to strong. This is excellent for experienced surfers – it’s got power and shape for a point, but that’s heavy for beginners, no doubt. The afternoon cleans up even more: glassy conditions, 8ft swell out of the S at 13 seconds, energy skyrocketing. This is the pick of the whole window. That long period south swell will wrap nicely around here since it’s a point, so the sets will be clean and lined up, but you’ll have some lulls between them. Crowds are *sometimes* a thing here, so keep your head on a swivel.
The next good moment pops up on Thursday, September 10th. The afternoon turns glassy, dead calm, with a 6ft easterly swell – short period at 7 seconds, so it’ll be a bit junky in the face, but the energy is moderate and conditions are very good for the average surfer that day.
There’s not much else to write home about. The run from September 3rd to the 9th is mostly poor with onshore winds or weak swell, except for a glassy window on the 3rd afternoon that’s just “good” but nothing special. And on September 11th, a strong 28 mph cross-off wind from the SSW blows in with an 8ft swell, but that wind strength will be a battle. That setup with the beach-and-reef nature might actually be more fun for kite surfing than paddling.
Overall, the first week is nearly a blank until the 1st, then Wednesday the 2nd is the absolute gem. The second week has one clean afternoon on the 10th but otherwise it’s looking patchy. Keep your eyes on that Wednesday – that’s the one.
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.

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.
