The Lowdown
Mate, Rusty here. Let’s take a look at what’s on offer at Praia do Aventureiro over the next couple of weeks.
Alright, so the outlook starts off with a bit of a wait. The first surf that’s really worth paddling out for is on Sunday morning, the 23rd of August. Before that, Saturday afternoon the 22nd has some chest-high swell but it’s cross-shore and a bit messy, so I’d sit it out.
Sunday morning, 23rd August – This is the standout of the early window. We’ve got a 4.9ft south swell, with a period of 10 seconds, rolling in with *glass* conditions – absolutely dead calm, offshore wind from the NE at 3 mph. The water is sitting at 73.8°, which is much warmer than normal for this time of year, a real bonus. The combined energy is a moderate 438. It’s a point break, very consistent, and it’s a beginner-friendly wave. The swell direction is from the south, and the optimum swell direction for this spot is east, so it’s not a perfect match, but the clean conditions and the ease of the wave make it a solid choice.
Sunday afternoon – The wind swings ESE and picks up to 9 mph, turning it cross-onshore and choppy. The swell drops a little, but it’s not worth it. Skip it.
Monday 24th – We get a bigger pulse of swell, 7.2ft to 7.9ft from the south, with a longer period of 13 seconds. The energy jumps way up – 1633 in the morning, 2031 in the afternoon. That’s strong wave energy. But the wind is onshore or cross-onshore from the SE, with light rain, making it choppy and messy. The report says marginal surf or questionable tides. For a beginner point break, this size starts to get a bit much, and the wind is just junk. Not the day.
Tuesday 25th to Wednesday 26th – Swell stays solid, around 6.6ft to 7.2ft from the south, with a very long period of 14 to 16 seconds. That’s proper groundswell. The energy is very strong, over 1900. The wind is light from the east or ENE, so it’s offshore, but the report keeps calling it “marginal” – likely a tide issue or something with the shape. This is a point break, so a long period south swell could wrap in nicely, but the conditions are marked as unknown or questionable. For a beginner spot, this is now in the “too big” territory, over 6.6ft, so it’s only for experienced surfers who know the place.
Thursday morning, 27th August – This is the real standout. The morning is clear, with zero wind – glassy. We’ve got a 5.9ft swell from the SSE, with a 14-second period. The energy is strong at 1558. The report says “excellent surf conditions for experienced surfers.” The wind is offshore (ENE at 0), the swell is a solid size, and the period is long. This is a point break, so a long period SSE swell should wrap in beautifully and offer some proper, clean lines. This is the session to aim for if you’re an intermediate or above. The water is still warm, but the anomaly is only shown for the first entry, so assume it’s still pleasant.
Thursday afternoon – The wind picks up a little from the SE, making it cross-onshore and choppy. The swell drops a touch. Not as good as the morning.
Friday 28th – The swell drops and shifts to the east, with a short period of 8 seconds. The energy is moderate. The wind is light cross-shore in the morning, but it’s a weak, short-period swell. Not great.
Saturday 29th to Sunday 30th – The swell collapses. Sizes drop to 2.3ft-3.6ft, with short periods. The wind is either glassy or cross-shore, but the energy is weak (around 100-200). The report says poor or very ordinary conditions. Not worth a paddle.
Monday 31st – Swell is tiny

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.
