The Lowdown
Alright, Rusty here. Let’s break down what Praia Tenório has on offer for the next couple of weeks. It’s a slow start, but there’s some quality to be had if you’re patient.
The first few days are a washout. Sunday the 6th is a complete loss with rain and onshore winds, the ocean is a mess. We’ve got a wait on our hands until Monday morning.
That Monday the 7th is the real deal. A south swell pushes in at a solid 6 ft, with a long 11-second period giving it some real punch and shape. The combined energy is a solid 734 (moderate wave energy), and the wind is glassy offshore from the NW. This is where you want to be. Praia Tenório cleans right up, offering some really nice, powerful lines off that south swell. The water is sitting at 73°F, which is a touch warmer than normal for this time of year – a nice little bonus. It’s a consistent break and fairly exposed to the swell, so you’ll get your share. Just be aware the crowds can be *sometimes* an issue, but for waves this good with glassy conditions, it’s worth it. This is your standout of the whole run.
Monday afternoon backs off a touch to 5 ft, but it’s still clean and fun with glassy conditions. The next few days, Tuesday through Thursday, drop in size and energy. You’re looking at small, clean but very ordinary surf – good for a beginner-plus session but nothing to write home about. Friday the 11th is a no-go again with onshores, and Saturday the 12th is tiny with a moderate offshore that just can’t make something out of nothing. The next week has a lot of rain and onshore wind, making for poor surf conditions.
Hold on, because Saturday the 19th and Sunday the 20th have some potential. That Saturday morning shows a solid 4 ft south-southeast swell with a very long 17-second period and combined energy of 798 (moderate wave energy). It’s clean and glassy. That’s a proper groundswell. That long of a period can make a beach break a bit straight and tricky, but the quality of the swell and the glassy conditions make it a serious contender for the best of the second week. Saturday afternoon gets bigger at 5 ft with a 16-second period and energy jumping to 1255 (strong wave energy), but the wind goes cross-shore so it won’t be as clean. Sunday the 20th morning is still a good call, with clean 4 ft surf and a 14-second period. After that, things wind down into small, onshore slop for the final days.
So, the pick of the litter is Monday the 7th for that punchy, clean south swell. For the long-range, keep an eye on Saturday the 19th and Sunday the 20th for that long-period groundswell. A bit of a wait, but the potential is real.
Rusty.

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.
