Praia do Aventureiro Surf Forecast and Surf Report

Alright, this is Rusty.

Look, it’s been a rough stretch lately and the next few days are going to be pretty ordinary for the most part, but there are a couple of windows that are worth getting excited about if you’re patient. The general pattern is a slow decline in swell size before a rebuilding stage that offers a couple of standout mornings later in the run.

We kick off with Praia do Aventureiro on Monday the 24th. The swell is hanging in there at around 7 ft but it’s coming from the S with a solid 13-second period. That’s a decent groundswell but the wind is a problem—ESE at 9 mph, blowing onshore, making things messy. The combined energy is strong (1661) but the quality is questionable. Don’t bother paddling out Monday; it’s not worth the frustration.

Tuesday the 25th is more of the same with waist-to-shoulder high waves but even more wind and a poor outlook. The swell is still S at 7 ft with 14-second periods but it’s onshore again. Not your day.

Now, Wednesday the 26th. This is where it starts to get interesting. Morning glass-off – dead calm, zero wind, and leftover S swell at 5 ft with a 12-second period. The combined energy is moderate (1302). The conditions are expected to be very good. Get out there early for clean, glassy walls. This is your first real window.

Thursday the 27th is the standout of the first week. Morning brings glassy conditions again, NNE breeze at just 3 mph, with a solid 6 ft SSE swell and a long 14-second period. The combined energy is up there at 1739. The water temp feels about average for late August, nothing weird going on. This is a beautiful setup for experienced surfers—the long period will produce powerful, lined-up waves at this point break. The crowds can be there sometimes, but with this quality, it’s worth it. Afternoon sees a risk of storms but a clean cross-off breeze at 6 mph, so there’s still fun to be had.

Friday the 28th through to Monday the 1st of September is a bit of a lull. Swell drops quickly to under 3 ft, periods shorten, and energy dips into the low 100s and 200s. There’s a small window on Sunday the 31st with a bit of clean cross-off breeze, but the waves are gutless. Keep the board in the car, maybe go for a paddle.

Tuesday the 2nd of September marks a shift. Morning brings clean offshore wind from the W at 3 mph and a building S swell at 5 ft. The period is short though, at 9 seconds (windswell), and the combined energy is moderate (407). It’s clean and rideable but not the quality of the previous week’s glassy days. The afternoon is messy with cross-shore wind.

Wednesday the 3rd and Thursday the 4th are blown out with onshore winds again. Friday the 5th of September is a serious contender for the best of the second week. Morning sees a W offshore breeze at 3 mph, glassy clean conditions, and S swell at 4 ft with an 11-second period. The energy is moderate (383). It’s not big, but it will be clean, fun, and empty-feeling. That’s a gem for the patient surfer.

After that, Saturday the 6th and Sunday the 7th drop off again into small, weak, onshore conditions. The final day in the window, Tuesday the 8th of September, shows a pulse of E swell at 6 ft with an 8-second period and cross-onshore wind. The energy climbs to 594 but the period is short, so it’s more of a messy, lumpy option for the die-hards.

Overall, the absolute best windows are the mornings of Wednesday the 26th of August and Thursday the 27th of August for glassy, powerful, long-period groundswell. The second week’s best is Friday the 5th of September for clean small waves with a good vibe.

Rusty.
