The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Praia de Asturias over the next couple of weeks.
We’ve got a bit of a slow starter, but once it gets going, there are some clean windows to keep an eye on. The water is sitting at 70°, which is a touch warmer than usual for this time of year, so that’s a nice little bonus.
The action kicks off on Tuesday afternoon, 25th August. It’s not huge, but there’s a 4ft swell ticking in from the south with a 13-second period, and the combined wave energy is solid at 597. Glassy conditions with a light NNW breeze mean the surface will be clean. It’s a bit inconsistent here, so don’t expect non-stop action, but when the sets come, it’ll be worth it.
Wednesday morning, 26th August, looks even better. A bigger, longer-period SSE groundswell at 4ft and 16 seconds pushes the energy right up to 910, and with dead calm, glassy conditions, you’ll be looking at some real quality. This is the standout of the first few days.
Thursday morning, 27th August, is another glassy one with 5ft of SSE swell at 15 seconds. Energy is still high at 852. The period is long, so it’ll be a bit on the fat side at a beachy, but for a point or reef, that’s gold. It stays clean and inviting.
Friday morning, 28th August, offers 5ft of short-period E swell (only 8 seconds) but the glassy NE breeze keeps it tidy. Energy is moderate at 563. Definitely worth a paddle before the onshores kick in later.
From there, things start to drop off fast. Saturday 29th and Sunday 30th are small and weak, with energy dropping below 100. That’s basically flat by any standard.
There’s a long gap of quiet, ordinary conditions from Sunday 30th right through to Wednesday 2nd September. The swell tries to pick up on the 2nd with a 6ft SSW swell, but 18-22 mph cross-off winds make it messy and blown out. That one’s for the kites, not for paddles.
The next real highlight comes on Thursday morning, 3rd September. We get a 6ft SSE swell at 10 seconds, and with glassy conditions and the NNE breeze at 3 mph, this will be clean and punchy. Energy is moderate at 546. That’s a beauty.
After that, the trend fades again. Friday 4th morning has a little 4ft SSE swell and glassy wind, but it’s only ordinary. The rest of the second week is a mixed bag of small, weak, and onshore winds. Nothing to get too excited about, but Monday 7th and Tuesday 8th September have a bit of S swell with reasonable periods (12-15 seconds) and light cross-off breezes, so you could snag a clean little wave if you time it right.
Overall, the best windows are the first Thursday morning (27th August) and the second Thursday morning (3rd September) – both glassy, both with solid groundswell. The early week is the most reliable; the later stuff is promising but less certain.
Keep your eyes on the sky, and don’t sleep on those Thursday mornings.
Rusty.

Information about the Praia de Asturias Surf forecast
The above surf forecast table for Praia de Asturias provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia de Asturias can be found by selecting the local surf guide option on the grey menu. Our Praia de Asturias 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 de Asturias) 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 de Asturias 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.
Praia de Asturias is 14 km (9 miles) from the city of Praia Grande. If you plan a holiday in São Paulo, look for hotels and other accommodation in Praia Grande. Praia Grande has rooms for a wide range of budgets as well as car hire and transport links.
