The Lowdown
Alright, Rusty here. Let’s break down what’s shakin’ at Praia do Aventureiro for the next couple of weeks. It’s a slow start, but there’s a couple of gems if you’re patient.
The water’s running at about 72°, which is a touch warmer than usual for this time of year – you’ll feel that extra bit of bathwater temp.
We kick off with nada worth paddling for until Tuesday, August 18th. That Tuesday morning is our first real standout: glassy conditions, a 2ft easterly swell with a period around 8 seconds, and the combined energy is 493 (moderate). The wind is dead calm, so it’s gonna be smooth as a mirror. This is a beginner-friendly point break, consistent, but it can get a bit busy sometimes.
Then we hit a flat spell through the middle of the week. Wednesday the 19th has some tiny 1.0ft waves but the energy is only 119 (weak). Thursday and Friday are small and ordinary. Saturday the 22nd is a washout.
The next real highlight lands on Sunday, August 23rd. Morning is glassy again, with a south swell at 1ft and a period of 11 seconds (solid groundswell). The energy is 401 (moderate). But the afternoon is the money session: a clean cross-off wind, a 2ft south swell, and the energy hits 571 (moderate). That Sunday afternoon is the pick of the whole forecast – decent size, clean, and that point break will love the longer period.
Monday the 24th brings the biggest swell, but it’s messy. The morning has 3ft from the south, period 11 seconds, and the combined energy is a chunky 1595 (strong). That’s expert territory – too big for most. The wind is a cross-shore mess, so it’s more for the kite crowd than us. The afternoon drops to 2ft with cleaner cross-off wind, but it’s still substantial.
After that, it fades. There’s a tiny, glassy 1.0ft morning on Wednesday the 26th of August, but the energy is only 324 (moderate) – a cruiser for a longboard. The last flicker is Monday, August 31st morning: a 0.8ft south swell with a very long 13 second period and clean cross-off wind. Energy is 277 (moderate). Small, but lined up.
Bottom line: Sunday the 23rd is your best bet. Circle it.
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.
