The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Praia Tenório over the next couple of weeks.
Right off the bat, we've got a bit of a slow start. The first record shows a small, cross-onshore wave on Sunday morning, but it's a no-go. The real action doesn't kick in until Monday morning the 10th. That's when we see a nice pulse of 5ft southerly swell with a 12-second period. The combined energy of all swells directed here is moderate (736). The real beauty is that the wind is glassy, and that's a major positive. The water is sitting at 73°, which is a touch warmer than normal for this time of year. That's a nice little bonus.
That Monday morning is the standout of the whole window. But it's a short-lived peak. By Monday afternoon, the wind swings onshore, and the quality drops.
The surf holds up through Tuesday and Wednesday, maintaining that 5ft to 6ft range from the SSE, with moderate energy levels peaking at 1139 on Tuesday afternoon. But the wind is cross or cross-onshore, so it's not going to be as clean as Monday morning. The period stays solid at 12-13 seconds, which is a good, long groundswell, so those waves will have some punch.
We get a few more windows of cleaner conditions with glassy mornings from Thursday the 13th right through to Sunday the 16th. The swell has dropped back to 4ft to 4ft by then, with moderate energy around 400-600. These are fun, clean waves, but they're not the standout. The morning glass-offs are the key here.
After the 16th, it all fades fast. The swell drops below 3ft, and the energy tanks into the double digits. We're looking at a long stretch of tiny, poor surf from the 17th all the way through to the 24th. There's a little blip on the 20th with a 3ft swell from the SSW, but it's a short-period windswell (6 seconds) and the wind is onshore, so it's more of a messy, choppy affair. The 23rd has a 3ft easterly swell, but again, period is a paltry 5 seconds. Not worth paddling out for.
So, bottom line: The best on offer is Monday morning, August 10th at Praia Tenório. It's the only time we get glassy conditions with a solid 5ft south groundswell. The rest of the first week has clean but smaller waves if you're keen, but after that, it's a wasteland for nearly a week. The setup is a beach, so with the choppy, windy conditions later on, it's looking more interesting for kite surfing than paddle surfing.
Rusty out.

Information about the Praia Tenório Surf forecast
The above surf forecast table for Praia Tenório provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Tenório can be found by selecting the local surf guide option on the grey menu. Our Praia Tenório 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 Tenório) 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 Tenório 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 Tenório is 4 km (2 miles) from the city of 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.
