The Lowdown

Imperial

Alright, listen up. Rusty here. We’ve got a bit of a slow start, but don’t write this one off just yet. The first few days are a dud, with hardly any push. Monday the 17th and Tuesday the 18th are basically flat with poor surf conditions, so save your energy. Wednesday morning the 19th gives us a tiny, glassy wave at Praia do Aventureiro, but it’s only 3ft from the east with a short period of 7 seconds – barely enough to get wet. The combined swell energy is a weak 122 (moderate wave energy), so it’s just a paddle-around session.

The real action starts to build from the 22nd. Saturday afternoon the 22nd sees a jump in size with a 5ft south swell, period 11 seconds, and a combined energy of 594 (moderate wave energy). The wind is cross-shore, so it’ll be a bit lumpy, but there’s some power. Then Sunday the 23rd afternoon is a standout – 4ft from the south, period 9 seconds, with a clean cross-offshore wind. The combined energy sits at 308 (moderate wave energy). This is the first real window of clean, fun waves.

Now, the big one. Tuesday morning the 25th of August. This is the pick of the whole forecast. The swell jumps to 8ft from the south with a very long 15-second period – that’s pure groundswell energy. The combined swell energy is a massive 2309 (strong to very strong wave energy). Winds are glassy calm, so the conditions will be epic. But listen, 8ft is expert territory. This is a reef/point break setup, so those long-period lines will wrap in nicely. Experienced surfers only.

Wednesday morning the 26th will still have solid 5ft south swell with a 13-second period and glassy conditions – a good follow-up session for the crew. The energy drops off after that. Thursday the 27th has a clean 3ft south swell in the morning, but by Friday the 28th it’s fading fast. The last week of August and into September, we’re looking at tiny waves, mostly under 3ft, with poor conditions. There’s a real gap from the 28th onward with no real recommendations.

The water here is 72°, which is a touch warmer than normal for this time of year – that’s a nice bonus.

So, the standout is Tuesday the 25th of August for the experts. The next best is Sunday the 23rd afternoon for a clean, manageable session.

Stay stoked.

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.
