The Lowdown
G’day, Rusty here. Let’s have a look at what’s shaping up for Pereque-Acu over the next couple of weeks. It’s a bit of a slow burn this time, with some patience needed, but there’s a couple of windows that’ll get the blood pumping if you time it right.
Right out of the gate, we’re not exactly firing. Wednesday afternoon (5 August) gives you tiny 2ft waves from the SSE with a glassy surface and a nice, long 11-second period. The water’s sitting at 72°, which is a touch warmer than normal for this time of year—that’s a bit of a treat for your bare skin. The combined energy is moderate (123), so it’s surfable, but honestly, just very ordinary. Not a standout. Thursday and Friday are flatliners with poor conditions and next-to-no swell, so don’t bother.
Now, Saturday afternoon (8 August) is where things start to get a little interesting. We see a jump to 6ft from the south, with a very long 15-second period—proper groundswell energy coming through. The combined energy is strong (1469), and that period means better shaped waves and longer lulls between sets, making the paddle out easier. But the wind is cross-onshore and light, and the forecast tags it as marginal. Given it’s a sheltered beginner spot, those longer-period south swells can line up nicely here, but the cross-onshore breeze will mess with the face a bit. It’s worth a look if you’re an experienced surfer, but it’s not perfect.
Sunday (9 August) holds 4ft from the south with a 13-second period, but the wind stays cross or cross-onshore, and conditions are poor. Skip it.
Monday morning (10 August) is the first real highlight. You’ve got 5ft from the SSE, 11-second period, and glassy conditions with a slight air. The combined energy is moderate to strong (572). The wind is glass and the water’s still a touch warmer than average. This is clean, fun-sized surf for Pereque-Acu. Not huge, but the offshore wind (E at 5 km/h) will keep it smooth. This is your best bet in the first week—get out there Monday morning.
Tuesday (11 August) and Wednesday (12 August) are a write-off with onshore winds and light rain messing up the shape.
Thursday morning (13 August) is another glassy moment. 4ft from the south, 12-second period, calm winds, combined energy moderate (468). It’s not big, but it’s clean. A good session for a beginner or someone wanting a cruisy ride without the hassle.
Friday through to Sunday (14-16 August) are messy. The swell holds around 4ft to 7ft on Sunday morning (16 August), but the wind is cross or cross-onshore, often choppy. That 7ft on Sunday morning from the SSE with a 13-second period has a strong 1520 energy reading, but that ENE cross wind at 10 km/h will kill the quality. For this sheltered beginner spot, that size and period might be a bit much anyway, and the conditions aren’t clean enough to make it a standout.
Monday (17 August) eases back to 3ft from the SSE, glassy, surfable but ordinary.
Then we look into the second week. The standout in the long range is Thursday morning (20 August). You’re looking at 4ft from the south, a 13-second period, combined energy moderate-strong (463), and glassy conditions with calm wind. This one is promising but less certain given how far out it is. Clean lines, good period, no wind—if it holds, that’s the best session of the entire forecast.
Overall, Pereque-Acu is a fairly consistent spot, and these gaps of poor days won’t last. Keep an eye on Monday 10th morning and Thursday 20th morning—those are your two windows for clean, enjoyable waves.
Rusty.

Information about the Pereque-Acu Surf forecast
The above surf forecast table for Pereque-Acu provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Pereque-Acu can be found by selecting the local surf guide option on the grey menu. Our Pereque-Acu 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 (Pereque-Acu) 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 Pereque-Acu 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.
Pereque-Acu is 2 km (1 miles) from Ubatuba. If you plan a holiday in São Paulo, look for hotels and other accommodation in Ubatuba. Ubatuba has rooms for a wide range of budgets as well as car hire and transport links.
