The Lowdown
Alright, Rusty here again. Let’s break down Praia do Aventureiro for the next couple weeks.
The first week is pretty flat and messy. Water temp is 73°, a touch warmer than usual, but the waves are lacking. From Monday August 31st through Wednesday September 2nd, the swell is tiny – mostly under 3 ft, with a short period of 6-8 seconds. The wind is all over the place, onshore or cross-off, and the energy is weak (67 to 163). Not worth gettin’ wet for a real session.
On Thursday September 3rd, the swell picks up to 5 ft from the SSE with a longer 11-second period and moderate energy (507), but the wind is cross-onshore at 6 mph, so it’s not clean. You can see it waking up, though.
The first standout is Friday morning, September 4th. Swell drops to 3 ft from the SSE, but that 11-second period gives it some punch. Wind goes glassy – 3 mph from the east – dead calm. Energy is still moderate (295). This is the call for a fun small-wave session on a longboard or fish. This point is very consistent, so there’s always a wave, but be ready for crowds.
After that, it gets rough from Saturday the 5th through most of the following week. Winds turn onshore and the swell builds from 5 ft on the 7th to over 7 ft by the 10th, but it’s choppy and blown out. Better for kite surfing than paddle surfing during that stretch.
Late in the forecast, Sunday September 13th afternoon is another good window. Cross-off wind from the southwest at 6 mph, 5 ft swell from the SSE at 7 seconds, moderate energy (305) and clean conditions.
The real gem, though, is Saturday morning, September 12th. Glassy winds from the SSW at 3 mph, 3 ft swell from the ESE with a nice 9-second period. Energy is low (147), but the conditions are perfect – clean, calm, and surfable. For a point break like this, that’s about as good as it gets.
Best bet: Friday September 4th morning for small clean waves, and Saturday September 12th morning for glassy, small perfection. The 13th afternoon is a solid backup. Skip the windy, messy days – they’ll only frustrate you.
Rusty.

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.
