The Lowdown
Right, listen up, crew. Rusty here. Let’s get stuck into what’s on the menu for Praia do Aventureiro. We’ve got a mixed bag coming, so let’s break it down.
We’re starting with a bit of a lull. The first few days are a write-off. Sunday the 13th is a no-go with cross-on wind and poor surf. Monday the 14th is a little better – glassy in the morning with 4ft from the SSE – but the quality is ordinary. Tuesday the 15th and Wednesday the 16th clean up a bit with light cross-off winds and some 3ft to 3ft waves from the south, but they’re small. The combined energy is weak to moderate (215 to 352).
Things get interesting on Thursday the 17th. We see the swell bump up to 5ft from the south with a period of 9–10 seconds, and the combined energy jumps to a moderate 498 to 780. The wind is onshore, though, so it’s marginal. It’s going to be messy. The bigger energy continues Friday the 18th with 4ft from the south (11-second period), but the wind is crap again – onshore and cross-on. Not worth the paddle.
Saturday the 19th is more of the same: onshore wind and rising swell up to 7ft from the ESE. That’s getting into expert-only territory if you’re brave enough to deal with the chop.
Now, here’s the standout. Sunday the 20th morning is the one to circle. We’ve got a 7ft swell from the east, but more importantly, it’s glassy. Dead calm. The combined energy is a strong 889, and the period is a short 8 seconds, so it’ll be a bit fat on the face, but with no wind it’ll be clean. This is a classic dawny. Get out there early. The water is a touch warmer than normal for this time of year, sitting at 73°, so no need for a thick suit.
After that, the surf drops off fast. Monday the 21st and Tuesday the 22nd see smaller waves and poor conditions. Wednesday the 23rd has a tiny clean 3ft from the ESE, but it’s barely worth mentioning. From there, we hit a real dry spell. Thursday the 24th right through to Sunday the 27th are all poor or ordinary. The swell is tiny – 2ft to 3ft – with onshore or cross-on wind. There is a small, glassy pulse on Saturday the 26th morning with 2ft from the south (12-second period), but it’s just surfable, not good.
The run finally ends on Monday the 28th with a small clean 4ft from the SSE, but the energy is weak (203) and the quality is still ordinary.
So to sum it up: the only real window is Sunday the 20th morning. Go early. The rest of the 16 days is mostly a waiting game. The spot is very consistent for waves, but the conditions are just not playing ball for most of it. The forecasts can change, but as it stands, don’t hold your breath.
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.
